What this PR does

Continues #5015 by androndo on a separate branch. All ten of their commits are kept as they were (authorship, messages and order, only rebased on current main). MariaDB and CNPG backups stored in S3 report Backup.status.artifact.sizeBytes, the size of the dump mariadb-operator uploaded or the total of the barman base backup, and the field stays unset when the size cannot be attributed to that one backup.

Four commits are added on top:

test(backups): operator Backup fixtures carry the condition mariadb-operator writes on success, Complete=True with reason JobComplete and message Success. Operator sets Complete=True for a failed Job too (reason JobFailed), so a fixture without reason describes a state that never happens. fix(mariadb): fail backup and restore jobs whose operator Job failed #5207 makes the driver check that reason, the tests pass with and without it.
refactor(backups): the MariaDB matcher returns the matched dump (key, file name, timestamp from the name, size, LastModified) and tells "not found" from "ambiguous", and the Secret lookup and S3 client live on a small value any reconciler can build from its own client. A MariaDB restore needs this to restore the dump of the Backup it was given and not the newest one under the prefix. sizeBytes does not change here.
fix(backups): the probe reads bucket, prefix, endpoint, credentials and TLS from the operator Backup's own spec.storage.s3, not from the strategy as it renders now, so editing the strategy during a backup does not send the probe somewhere else.
fix(backups): a dump is attributed only when its ownership is proven. Before, a backup pod with a clock more than a minute behind, right after a previous run, got that run's dump size (666 bytes for a 123-byte dump in a test). Now the dump has to be the only one that either clock places in the operator Backup's lifetime, both clocks have to agree, and neither may place it in the lifetime of another finished operator Backup with the same bucket and prefix. Otherwise the size stays unset. Two cases are still not covered. First, this run's own dump is missing from the listing while the operator Backup of a neighbour was deleted or has not finished, then the neighbour's dump can be taken. Second, backup pod clock and object store clock are both off the same way by more than the minute of slack, which moves a finished neighbour's dump into this run's window, and nothing the clocks record tells them apart. A run whose Job failed has no dump of its own and reaches the probe only because the driver takes Complete=True for success, fix(mariadb): fail backup and restore jobs whose operator Job failed #5207 fixes that.

Of the open threads on the original PR, the cache reads, the dump file name layout and the default AWS endpoint test were already handled by its later commits, the clock skew one is the last commit here and the failed Job case is #5207.

minio-go is new to this tree, this PR adds it as a direct dependency and internal/backupcontroller/artifact_size.go is its only importer. The open Bucket strategy PR #4235 picks the same client at the same version.

Each clock skew case, and a run whose own dump is gone while the neighbour's operator Backup still exists and has finished, have a unit test that fails on the old matcher, and every new guard has a mutant that turns a test red. I also ran the matcher against a real bucket after four MariaDB backups in a row. Runs that finished more than a minute apart mapped to the dump their operator Job logged, the two back to back came back unset instead of taking each other's dump, and with a run's own dump hidden from the listing the matcher refused the neighbour's dump that the old one returned.

Release note

fix(backups): MariaDB and CNPG (Postgres) backups stored in S3 now report `status.artifact.sizeBytes`: the size of the dump mariadb-operator uploaded, or the total size of the barman base backup (WAL archive excluded). A MariaDB backup takes the size of the one dump that falls inside its run on both the backup pod's and the object store's clock and inside no other finished run, and the size is left unset rather than set to 0 whenever it cannot be measured or attributed. Velero-based backups intentionally keep it unset.

Summary by CodeRabbit

New Features
- Backup artifacts now report the stored size attributable to an individual MariaDB or CNPG backup when it can be determined. Shared or ambiguous storage may leave the size unset.
Bug Fixes
- Improved handling of backup artifact creation and lookup errors, including retrying when an existing backup cannot be read and failing jobs when artifact creation is rejected.
Documentation
- Clarified that an unset size means unknown; zero does not indicate an unknown size.

Backup.status.artifact.sizeBytes was only ever set by the etcd strategy, so MariaDB backups always arrived without a size. mariadb-operator writes each logical dump as <prefix>/backup.<RFC3339>[.<compression>].sql under a prefix shared by every backup of the application, and the URI the driver records is synthetic, so there is no single object to HEAD. On completion the driver now lists the prefix with the tenant credentials the operator Backup was rendered with and takes the size of the one dump whose timestamp falls inside the operator Backup's lifetime. When the bucket cannot be read or the window does not match exactly one dump, the field stays unset. The API doc now states that an absent sizeBytes means "unknown", and the Velero strategy documents why it leaves the field unset: kopia stores data content-addressed across backups, so there is no per-backup stored size. Refs #4316 Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

CNPG backups arrived without Backup.status.artifact.sizeBytes: cnpg.io/Backup status carries no size, and the data lives in barman's object-store layout rather than in a single object. barman-cloud uploads every base backup under <destinationPath>/<serverName>/base/<backupID>/ (backup.info plus the data and tablespace tarballs, possibly split into parts). On completion the driver now lists that prefix with the credentials and endpoint CA of the rendered barmanObjectStore and records the total. The WAL archive is not counted: it is one stream shared by every base backup of the server. The field stays unset when the backup ID is unknown, the bucket cannot be read, or nothing is stored under the prefix. The S3 client and Secret lookup are now shared with the MariaDB driver. Refs #4316 Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

The probe runs inside the reconcile that creates the Backup, and the BackupJob controller has a single worker, so its timeout delays every other BackupJob while an endpoint hangs. Lower it from 30s to 10s. List the MariaDB prefix non-recursively, as mariadb-operator does. The default MariaDB prefix and the default CNPG destinationPath are the same <namespace>/<name>/ path, so a recursive listing of a MariaDB backed up next to a same-named Postgres walked the whole WAL archive and ran out of time. The CNPG base-backup prefix is still listed recursively. Build the custom-CA transport from minio.DefaultTransport so it keeps the proxy-from-environment and dial/TLS timeout settings a bare http.Transport drops, and cover it with a test against a TLS endpoint with a self-signed certificate. Log the reasons the size could not be measured (credentials, client, listing, empty CNPG prefix) at info. The chart runs the controller at info, which hid them before. The expected ambiguity of several MariaDB dumps in the window stays at debug. Skip an endpointCA without a Secret name, as buildBarmanObjectStore does. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

minio-go ends a listing whose context is cancelled between pages by closing the channel without an error item. When the probe timeout expired between pages of a large CNPG base backup, the pages already read were summed and reported as the measured size. Check the context once the listing channel closes and leave the size unset instead. The probe ran before the Backup was created, so a reconcile that retried after the Backup already existed probed the bucket again, held the single BackupJob worker for up to the timeout, and then discarded the result in favour of the existing object. Return an existing Backup before probing. Log the ambiguous MariaDB case (several dumps in the window) at info like the other reasons the size stays unset, and cover the session-token credential path with a test. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

An endpoint such as https://s3.example.org/prefix cannot be addressed by minio-go, which has no path-prefix option, and the prefix cannot be added below the client either, because the SigV4 signature covers the request path. The CNPG probe was worse than failing: it kept only the host of endpointURL and listed the bucket at a location barman never writes to. Reject such endpoints with an explicit error, in the CNPG probe and in the shared client, so the size is left unset instead of measured somewhere else. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

…uncached The MariaDB probe identified this run's dump by the timestamp in its file name, which comes from the backup pod's clock. With that clock skewed past the slack, this run's dump falls outside the window while a neighbouring run's dump can be the single match left, and its size is reported as this backup's. A dump now has to fall inside the window by both its name and its LastModified, which the object store stamps, so a single skewed clock leaves the size unset instead. The name parser also accepts the layout later mariadb-operator releases write for compressed dumps, backup.<ts>.sql.<ext>, and checks the compression token in either layout, so an operator upgrade does not silently stop the measurement. The retry check and the AlreadyExists refetch read the Backup through the cache. A retry usually follows a Create made moments earlier; a cache that does not show it yet turned the refetch into NotFound and failed a backup that had succeeded. Read it from the API server instead. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

The check for a Backup an earlier reconcile already created returned its read error, and the drivers turn any error from that path into a terminally Failed BackupJob. An apiserver timeout right after the operator backup completed therefore lost a backup whose data was safely in S3. The check only saves a probe, and the Create that follows already handles an existing Backup, so log the error and go on to Create. A trailing slash on the S3 endpoint is not a path prefix; the operators accept it, so do not refuse it. Pin the uncached AlreadyExists refetch, the upper slack of the MariaDB window and the probe timeout with tests. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

… be read When Create collides with a Backup an earlier reconcile already made and the read that follows fails, the drivers failed the BackupJob, although the backup and its Backup both exist. Return a distinct error instead, which the drivers hand back to the controller so the reconcile is retried with backoff and then finds the Backup. minio.New already refuses an endpoint with a path prefix and accepts a trailing slash, so drop the duplicate check in the shared client; the CNPG probe keeps its own check because it parses the URL itself and would otherwise drop the path before minio sees it. Say in the sizeBytes API doc what the value covers, such as the base backup without the shared WAL archive for CNPG, and that strategies which cannot attribute stored bytes to one backup leave it unset. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

…probe A Backup that exists but cannot be read back is retried through the controller's backoff, which left the BackupJob Running with nothing on it saying why. Set Ready=False with reason BackupNotReadBack before handing the error back. When the check for an existing Backup itself fails, the Backup may well exist, so a size probe would only be discarded, and a read that keeps failing reran it, up to the probe timeout on the single BackupJob worker, on every retry. Skip the probe in that case and create the Backup without a size. Drive both behaviours through the MariaDB and CNPG reconciles in tests. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

With an endpoint CA the probe trusted the system roots plus that CA. barman-cloud gets endpointCA as AWS_CA_BUNDLE, which replaces the default trust store, so a CNPG probe could accept an endpoint the backup itself would have refused. Let the connection say whether the CA adds to the system roots or replaces them, and replace them for CNPG. mariadb-operator appends its CA to the system pool, so MariaDB keeps that. Pin in reconcile tests that a Create the apiserver rejects still fails the BackupJob, so only the read-back of an existing Backup is retried. Assisted-by: LLM Signed-off-by: Andrey Kolkov <[email protected]>

mariadb-operator marks a Backup Complete=True for a failed Job as well as a successful one; only the reason tells them apart (JobComplete with message Success, or JobFailed with message Failed). The fixtures that stand for a finished backup set Complete=True and nothing else, so they describe a state the operator never produces and would read as a failure to a driver that checks the reason. Give them the success shape the operator writes. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

A MariaDB restore has to name the dump it restores from: without a target time the operator restores the newest dump under the prefix, which is not necessarily the one of the Backup being restored. The size probe already finds that dump, but it returns only its size, folds a missing, an ambiguous and an unreadable listing into the same 0, and lives on BackupJobReconciler, which the restore reconciler is not. Split the probe in two: findMariaDBDump reads the bucket and returns the matched object (key, file name, the timestamp in its name, size and LastModified) or an error that tells "not found" from "ambiguous"; the size path keeps its timeout and reads only the size. The Secret lookup and the S3 client move onto an objectStore value that any reconciler can build from its own client, and BackupJobReconciler keeps one-line wrappers so the CNPG probe is unchanged. sizeBytes is reported exactly as before. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

…e it The size probe took the bucket, endpoint, prefix, credentials and TLS settings from the strategy as it renders on the reconcile that creates the Backup, which is not necessarily what it rendered when the operator Backup was created: an existing operator Backup is reused untouched, and a backup can run for up to the driver's 30-minute deadline. An admin who edits the strategy in between sends the probe to the new location, where it measures the wrong prefix or nothing at all. The operator Backup's own spec.storage.s3 is where the dump went, so the probe reads that. It is also the only source a restore can use, since it targets that operator Backup long after the strategy may have changed. An operator Backup that does not store to S3 is refused before anything is listed. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

Every backup of a MariaDB application writes its dump under one shared prefix, so the probe took the dump whose file-name timestamp (the backup pod's clock) and LastModified (the object store's clock) both fall in the operator Backup's lifetime, with a minute of slack for skew. That keeps a neighbour's dump out only while this run's own dump is in the window. With the pod clock more than the slack behind, the own dump is named before the window opens, and a previous run that finished within the minute before this one was created becomes the single match: a 123-byte dump was reported as 666 bytes. A pod clock ahead or an object store clock behind does the same with the next run, and an own dump that is gone by the time it is looked up, as it can be for a restore long after the backup, leaves a neighbour as the single match with no skew at all. A dump is now attributed only when ownership is proven: - it is the one dump that either clock places in the window. A dump that one clock places there and the other does not may be this run's own with a skewed clock, so it leaves any other match unproven, the way a second dump in the window already did, and is not taken itself; - both of its clocks place it in the window; - neither clock places it in the window of another operator Backup that writes under the same bucket and prefix and has completed. This rejects a neighbour's dump when this run's own is missing, which the clocks alone cannot tell. Operator Backups still running are not counted as neighbours: their window has no end, and one stuck short of Complete (a Job whose pod never starts stays JobRunning for good) would otherwise keep every later run of the application from being sized. A dump such a run writes inside this run's window still competes with this run's own. Narrower slack does not prove ownership: a neighbour that finished within the narrower slack still matches, and a smaller skew pushes the own dump out. The Job's start and completion times are stamped by the control plane, like the operator Backup's own, so they narrow the window by seconds without removing the dependence on the two clocks a dump carries. What is left: a neighbour's dump is taken only when this run's own is missing from the listing or misplaced on both clocks and the neighbour's operator Backup no longer exists or has not completed. Every other unproven case leaves the size unset, as two runs that overlap or follow each other within the slack already did. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

Walkthrough

The backup controller now measures stored bytes attributable to CNPG base backups and MariaDB logical dumps, and records the measured size in backup artifacts. Shared S3 listing, endpoint trust, and artifact read-back handling support these probes. Size remains unset when it cannot be measured or attributed.

Changes: Backup artifact size attribution

Layer / File(s)	Summary
Shared artifact contract and S3 support `api/backups/v1alpha1/backup_types.go`, `packages/system/backup-controller/definitions/*`, `internal/backupcontroller/artifact_size.go`, `internal/backupcontroller/backupjob_controller.go`, `internal/backupcontroller/artifact_size_test.go`, `internal/backupcontroller/velerostrategy_controller.go`, `go.mod`	The API documentation defines size as bytes attributable to one backup and distinguishes unknown size from zero. Shared code adds S3 object listing, endpoint trust configuration, bounded probes, uncached Backup lookup, and retry handling for unreadable existing Backups.
CNPG base-backup size measurement `internal/backupcontroller/cnpg_artifact_size.go`, `internal/backupcontroller/cnpg_artifact_size_test.go`, `internal/backupcontroller/cnpgstrategy_controller.go`	The controller parses Barman S3 destinations, lists objects beneath the backup-specific base prefix, and sums their sizes. CNPG artifact creation records the measured size when a probe is requested.
MariaDB logical-dump attribution `internal/backupcontroller/mariadb_artifact_size.go`, `internal/backupcontroller/mariadb_artifact_size_test.go`, `internal/backupcontroller/mariadbstrategy_controller.go`	The controller matches recognized logical-dump files against the Backup time window and completed neighboring runs. MariaDB artifact creation records the matched object size when a probe is requested.

Explanation

Issue #4316 requires measurable MariaDB and CNPG artifact sizes, absence when the size is unknown, and no misleading Velero value. The PR adds MariaDB dump attribution and size propagation, CNPG base-backup size calculation that excludes shared WAL objects, and guards that leave the field unset when measurement or attribution fails. The API descriptions document these rules. The change includes focused tests for size calculation, attribution, failure cases, and propagation.

Build the MariaDB artifact URI from the operator Backup's storage.

The URI comes from the rendered strategy, but the size is measured at the operator Backup's own S3 location. After a mid-backup strategy edit, a Ready Backup can report a size for one bucket and a URI for another. Derive the URI from mdbBackup.Spec.Storage.S3 so both fields describe the same location.

Filter the S3 listing while it runs, or cap its entry count.

collectObjects appends every listed object before any caller filters the list. The 10-second timeout bounds time, not entry count. A large MariaDB prefix can exceed the controller's 128Mi memory limit during one probe. That can OOM-kill the pod and stall other BackupJobs.

Probe the size when the existence read fails.

When existingBackup gets a non-NotFound error, it returns probe=false. The Backup is then created without SizeBytes. Later reconciles return the existing Backup and never probe again, so a measurable size stays unset. Make the error path return probe=true, or backfill SizeBytes on the existing Backup.

Resolve the size probe from the destination the backup was written to.

The size probe reads rendered.BarmanObjectStore, which comes from the current strategy on each reconcile. The ObjectStore is also re-applied from that strategy on every reconcile. If the destination changes after the base backup uploads but before the artifact is created, the probe lists the new prefix, finds no base backup objects, and leaves the size unset. The data stays under the old destination. Applying the ObjectStore does not move it.

Use the destination that the completed backup used, rather than the current strategy value, when the probe runs.

Leave the size unset when this run's own dump is missing.

matchMariaDBDump returns an earlier run's retained dump when that run's operator Backup is deleted and this run's own dump lies outside the window on both clocks. The stored sizeBytes then reports another run's size. Leave the size unset in this case, and add a regression test.

Read neighboring operator Backups through the uncached reader.

finishedMariaDBRuns lists BackupList through the manager's cached client. A neighbor that completed just before the probe can be missing from the cache. If this run's own dump is also absent from the listing, the neighbor's dump passes the ownership check, and its size is stored on this Backup. The artifact-existence check already reads through the uncached reader.

Do not report a running neighbor's dump as this run's size.

When a run's own dump is missing from the listing, matchMariaDBDump returns the only dump in the window. That dump can belong to a neighbor whose operator Backup is still running, because finishedMariaDBRuns skips unfinished neighbors. The run then reports the neighbor's sizeBytes. Leave the size unset in this case, and add a test for a missing own dump with an unfinished neighbor dump in the window.

Verdict: LGTM

Reviewed the two-clock matcher and the shared S3 layer. One angle worth recording because it looks like a hole and is not: finishedMariaDBRuns keeps only neighbours with Complete=True, and a reader might expect that to drop terminally-failed runs from the exclusion set. It does not: mariadb-operator's SetCompleteWithJob (pkg/condition/complete.go, v25.10.2) sets Complete=True / JobFailed on a failed one-shot Job, so a failed neighbour stays in others and still contests a dump that falls in its window. The comment ("whether their Job succeeded or failed") matches the behaviour. The two documented clock-skew cases leave the size unset rather than attributing a wrong one, which is the safe direction.

Non-blocking:

No test covers a Complete=True / JobFailed neighbour that left a listable object. Adding one would pin the intent above and guard it against a future change that keys the filter on the reason.
minio-go is a new direct dependency and pulls ~8 transitive ones; it is the only importer and there is no existing AWS client to reuse, so the dependency is justified, just noting the surface.
sizeBytes is now populated for etcd, CNPG and MariaDB, but not for clickhouse/altinity, so #4316 is only partly closed.

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -

follow-up: ### Release note ```release-note fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository. fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout. fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member. fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade. fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint. fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...＠sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time. fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back. fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking. fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts. fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result. fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand. fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing. fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret. fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain. fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged. fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane. fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged. fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase. fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading. fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix. fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring. ```

…ckups (#5046) ## What this PR does Builds on the shared S3 probe from #5223 (MariaDB and CNPG), which is on `main`. Refs #4316. Backups made by the Redis strategy carry no `Backup.status.artifact` at all: no URI and no size. This covers both the Redis and Valkey apps, which share the driver. The snapshot is a single object per backup, `<namespace>/<app>/<backup>.rdb` (`redisObjectKey`). The driver already records that key in `driverMetadata`. The default strategy uploads the object using the S3 coordinates from the backup credentials Secret, which the controller projects into the application namespace (`endpoint`, `bucketName`, `region` and the access keys). When a backup completes, the driver now: 1. reads that projected Secret (`CredentialsConfig.TargetSecretName`) in the application namespace. The projector stores its `endpoint` without a scheme, and the strategy script reaches it over https; an endpoint with a path prefix is refused by minio-go, which leaves the artifact unset; 2. reads the TLS trust from the pod spec of the completed backup Job, in the order the script applies it: `ca.crt`, then `tls.crt`, from the Secret mounted as the `s3-ca` volume (`backupStorage.endpointCASecretName`). Only when there is no `s3-ca` volume does it honour `S3_INSECURE_SKIP_VERIFY=true`, and only when every container of the pod sets it, since the probe cannot tell which container uploaded. The Secret is read at probe time; the default strategy mounts `s3-ca` only when an endpoint CA is configured, so when the volume yields no CA now (the Secret is gone or lacks both keys, or the volume is not a Secret), the probe leaves the artifact unset rather than trust the system roots or skip verification where the Job may have verified. The CA is trusted on its own, as `curl --cacert` does, not on top of the system roots; 3. runs `StatObject` on the recorded key; a response without `Content-Length`, which minio-go reports as size -1, counts as unmeasured; 4. records `status.artifact.uri = s3://<bucket>/<key>` and `status.artifact.sizeBytes` = the object's size. An empty object is recorded too, but `sizeBytes` is `omitempty`, so on the Backup it reads like an unmeasured size; since a valid RDB snapshot always carries a header, a Warning `EmptySnapshot` Event on the BackupJob flags it as a broken backup. The artifact is set **only when the object is found**. A custom strategy that writes elsewhere would otherwise get a URI pointing at an object that does not exist. On any failure (Secret missing or incomplete, endpoint invalid, CA unreadable, object not found, TLS error) the artifact stays absent and the backup still succeeds. The full error is logged at info, and once the Backup is created a Normal `ArtifactNotMeasured` Event on the BackupJob gives a fixed reason, also when a failed existence check skipped the probe; the Event lives in the application namespace, so it never carries the raw error, which may name the platform's endpoint and bucket. The probe shares the 10s timeout of the MariaDB and CNPG probes. The retry check is shared with those drivers too: a `Backup` that already exists is returned without probing, a failed existence check creates the Backup without probing, a `Create` collision is resolved by reading past the cache, and an existing Backup that cannot be read back is retried with `Ready=False` instead of failing the BackupJob. The size is useful because an RDB snapshot is the compressed dataset. It shows growth, and a snapshot that is suddenly tiny is a broken backup. Kafka is deliberately left out. Its backup is a topic-metadata export of a few kilobytes, so the size would say nothing about the data and might suggest the data itself was backed up. Tests: - the stat uses the projected credentials; - every path that leaves the artifact unset: object missing, Secret missing, bucket, endpoint, access key or secret key missing, no target Secret configured, a size the endpoint did not report; - trust resolution: `ca.crt` wins over `tls.crt` and skip-verify; `items` remapping of the volume, and a key the `items` do not project is never trusted; the Redis CA volume mounted next to `s3-ca` is not taken as the S3 CA; an `s3-ca` volume that yields no CA (Secret gone, Secret without the keys, a ConfigMap source) is refused with and without skip-verify; skip-verify applies only on an exact `true` of that variable in every container, the last entry of a repeated variable winning; - the real minio client against a TLS stub: its certificate is trusted only through the `s3-ca` volume or skip-verify, a CA that did not sign it is refused even with skip-verify set on the Job, and the shared client enforces a configured CA with and without the system roots; the client sends a signed `HEAD` and parses `Content-Length`; - the Events: an unmeasured artifact or a failed existence check raises `ArtifactNotMeasured` without the raw error; an empty snapshot is recorded and raises a Warning `EmptySnapshot`; a measured artifact, a rejected `Create` and a `Create` collision raise none; - a reconcile test pinning that the completed Job's pod spec reaches the probe; a Backup that already exists is returned without a probe or a `Create`; the `Create` collision is read back from the API server past the cache. The suite fails if any guard of the trust lookup (volume name, Secret source, variable name, every-container rule, refusal of an unreadable CA), the CA enforcement in the transport, the negative-size check, the Events, the reason-only message, their place after `Create`, the empty-snapshot warning, the existing-Backup check, the wiring, any term of the Secret check, or the API-server read-back is removed. ### Screenshots N/A — no UI changes. ### Downstream repositories I walked the trigger map against the diff. The change is Go-only in `internal/backupcontroller`, with no API, CRD, chart, value or schema change. Existing `Backup` fields are now filled for one more driver. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(backups): Redis and Valkey backups now record `status.artifact` with the `s3://` location and the size of the RDB snapshot. If the snapshot cannot be found with the platform backup credentials, the artifact stays unset and a Normal `ArtifactNotMeasured` Event on the BackupJob says why. An empty snapshot raises a Warning `EmptySnapshot` Event. ```   ## Summary by CodeRabbit * **New Features** * Redis backups now include artifact location and size when they can be measured. * Backups are still created when artifact measurement fails, with status reporting that the artifact was not measured. * **Bug Fixes** * Improved handling of existing backups and temporary read-back failures to support reliable reconciliation. * Improved compatibility with S3 endpoints using custom certificate authorities or configured TLS verification settings. * Zero-size snapshots are now reported with a warning.

## What this PR does Backports to `release-1.7` from `main`, picked by the rules of the [backport policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md) in merge order. A merged pull request comes as its own commits, picked with `git cherry-pick -x` so each keeps its author, message and sign-offs, and a merge commit that carries the original's merge message with a `Backported-from:` trailer naming it; a squash-merged one comes as one pick. `backport-batch verify` checks that shape. A pick listed as changed differs from the commit it came from; `git range-diff <merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A conflict or a failing check here is a [backport task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md). -

COSI driver is bumped to v0.4.0, which writes each grant to per-identity IAM file. ```

#5233) ## What this PR does Deleting a MariaDB `Backup` removed only the Cozystack object: the dump stayed in the bucket and the `k8s.mariadb.com/Backup` stayed in the namespace. Nothing else prunes such a dump on the platform bucket. mariadb-operator's `maxRetention` runs only inside the next backup run of the same prefix, and a `Plan` never deletes a `Backup`. Deleting a MariaDB `Backup` now deletes its dump, then the operator `Backup` that wrote it, and only then lets the `Backup` go. Every run of an application writes under the same prefix, so the only key ever deleted is one proven to belong to this `Backup`: - a `Backup` taken with #5227 records its dump in `driverMetadata` (`k8s.mariadb.com/dump-file`), and that key is deleted unless another run of the same prefix, finished or not, could have written it. The size probe that records the name lets only runs finished by then contest it, so a run that uploaded its dump and pruned this one through `maxRetention` before completing can have its dump recorded here; the delete contests the recorded dump again against every run as it stands, keeps it when any could own it, and releases the `Backup` with a `Warning`; - a `Backup` taken before that is matched with the same ownership-proven attribution #5223 introduced for the size probe and #5227 uses for legacy restores: one dump in the operator `Backup`'s lifetime on both clocks (the timestamp in the name and `LastModified`), and in the lifetime of no other run of the same prefix, finished or not: a run that has not completed yet may already have uploaded its dump and pruned this one through `maxRetention`, so its window is treated as still open. The match is recorded on the `Backup` before the delete, so a retry deletes the same key by name; - when no dump is proven, the `Backup` is released with a `Warning` event and nothing is deleted, the operator `Backup` included, since it is what any later attribution starts from. The delete runs inside the controller through the minio client #5223 added, the same library mariadb-operator writes with, so TLS is verified the same way. Bucket, prefix and dump name come from the operator `Backup`. When the operator `Backup` writes to the platform bucket, which it names by the bucket and by the projected `cozy-backups-creds` Secret, the endpoint and keys are the platform's current ones (read from the Secret `cozy-backups-creds` is projected from, TLS from the scheme of the platform endpoint, as the default strategy decides it, still trusting a CA the strategy pinned), so a `Backup` taken before the endpoint moved is still deleted. Any other bucket is reached as the operator `Backup` recorded it. Other cases: - a restore from the `Backup` holds the deletion while it runs: a `RestoreJob` of the `Backup` that has not finished, or an operator `Restore` of its operator `Backup` that mariadb-operator has not marked `Complete` (it does so once the Restore's Job has completed or failed). The second check matters because a `RestoreJob` can fail on its deadline while its operator `Restore` keeps reading the dump. Both are listed from the API server rather than the informer cache, so a restore that started just before the delete is not missed; - a restore does not start from a `Backup` that is being deleted or is gone: the MariaDB restore reads the `Backup` from the API server before creating the operator `Restore` and fails the `RestoreJob` otherwise, since mariadb-operator restores the nearest other dump once the requested one is deleted. A failed lookup of an existing operator `Restore` is retried rather than failing the `RestoreJob`; - a failed dump delete keeps the `Backup` in `Terminating` and retries every 30 seconds with a `Warning` naming the `backups.cozystack.io/skip-artifact-cleanup` annotation, which releases the `Backup` and deletes nothing; a failed delete of the operator `Backup` is retried with the controller's backoff; - a missing or malformed platform credentials Secret falls back to the credentials the operator `Backup` names, so it never releases a `Backup` on its own: a delete that then fails holds it as above. A failed read of that Secret (an API error) is retried instead, because the recorded endpoint may be the one the platform moved off; - a recorded dump that is not in the listing is not deleted again: the operator `Backup` is deleted and a `Normal` `ArtifactAlreadyAbsent` event names the key and the endpoint that was listed, so a dump left on storage the platform moved off can still be found; - in a terminating namespace a failed delete releases the `Backup` with a `Warning`, so it does not hold the namespace; - an operator `Backup` that is gone, that stores on a PVC or volume, or whose Job failed (`Complete=True` with reason `JobFailed`, which wrote no dump) releases the `Backup` with a `Warning` and nothing is deleted, as does a cluster without the mariadb-operator CRDs. The controller gains the `delete` verb on `k8s.mariadb.com/backups`. No Job, image or flag is added. Known limitation: when a namespace is deleted with its `Backup`s, the namespace controller may delete the operator `Backup` first, and the `Backup` is then released with a `Warning` and its dump left behind, because the bucket and prefix are read from the operator `Backup`. Known limitation: an operator `Backup` that never completes, for example one whose Job pod never starts, contests every later dump its lifetime covers on that prefix, so those `Backup`s are released with a `Warning` and their dumps left behind. That leaks storage rather than deleting a dump another `Backup` may restore from. The contest reads the runs from the operator `Backup`s that still exist, so a run whose operator `Backup` was deleted by hand no longer contests a dump. Likewise, an operator `Restore` that never completes holds its `Backup`'s deletion until the skip annotation releases it. These and the namespace-teardown limitation above are tracked in #5291. Stacked on #5227 and targets its branch until that merges; only the commits after #5227's head belong here. Tests: controller tests on the fake client cover each path above, including the window bound (`takenAt`, not the operator's `Complete` transition) of the legacy match, ordering (the operator `Backup` survives a failed dump delete, and a legacy `Backup` retried after a failed operator `Backup` delete finishes by its recorded name) and the finalizer at `Reconcile` level. The minio adapter is tested against an HTTP server for the escaped key and an error response. A helm-unittest pins the RBAC verbs. An unfinished neighbour run is covered both ways: one that started inside the `Backup`'s lifetime keeps its candidate dump, one that started after it does not contest an earlier dump. The coordination with restores is covered from both sides: a `RestoreJob` or operator `Restore` that has not finished, including one only the API server has seen yet, holds the deletion, and a restore from a `Backup` being deleted or gone is refused without creating an operator `Restore`. A recorded dump is contested the same way, down to the full sequence of the size probe recording a dump an unfinished run uploaded and the `Backup` then being deleted, and a recorded dump already gone is not contested. Every condition was mutated, each mutation turns a test red, including the timeout that bounds an unreachable endpoint. Checked on a test cluster against SeaweedFS with the controller function and its real minio client: over the in-cluster `seaweedfs-s3.<ns>:8333` endpoint with its wildcard certificate a recorded dump and a legacy dump were deleted with their operator `Backup`s, a neighbouring dump was kept, and a recorded dump already gone completed; with a dead recorded endpoint the dump on the platform bucket was deleted through the platform's current endpoint; on a foreign bucket behind a dead endpoint the `Backup` was held with everything kept. The contest of a recorded dump and the coordination with restores were added after that run and are covered by the controller tests only. ### Screenshots Not a UI change. ### Downstream repositories Walked against the diff.

Only a dump proven to be the Backup's own is deleted: the one it records, unless another run could have written it, or for older Backups the one that can be attributed to its run. Otherwise the Backup is released with a Warning event and nothing is deleted. A failed delete keeps the Backup Terminating and retries; the backups.cozystack.io/skip-artifact-cleanup annotation releases it and keeps the dump. Deletion waits while a RestoreJob or an operator Restore reads the Backup's dump, and a restore from a Backup being deleted is refused. ```

## What this PR does A RestoreJob that names a MariaDB `Backup` restored the newest dump of the application, not the dump of that `Backup`. The driver created the operator `Restore` with only `backupRef`, and mariadb-operator then restores the dump nearest to the moment the restore starts, from the prefix every run of the app shares. Restoring an older `Backup` brought back the latest data, and when its own dump was already gone it silently restored another one. The `Backup` now records the dump its operator `Backup` wrote, the file name in `k8s.mariadb.com/dump-file` and the timestamp from that name in `k8s.mariadb.com/dump-time`. They come from the ownership-proven match the size probe already makes, and nothing is recorded when ownership is not proven. A restore first checks with a bounded S3 listing of the operator `Backup`'s own storage that the dump still exists, then sets `targetRecoveryTime` on the operator `Restore` to the dump's own timestamp, which mariadb-operator matches exactly. If the dump is gone the RestoreJob fails and names it. If the check cannot be made it waits with `Ready=False/DumpCheckPending` until the restore deadline and then fails with the cause. `Backup`s taken before this stay restorable. The restore makes the same ownership-proven match against their operator `Backup` and pins the dump when it is provable, otherwise it restores the newest dump as before and a `BestEffortDump` warning event on the RestoreJob says so. One case is not covered: the `Backup`'s own dump is gone, a neighbour's dump from within the minute of slack is still there and its operator `Backup` was deleted, so that dump is taken as the match. Nothing in the platform deletes operator `Backup`s, it needs someone to delete one by hand. A `Backup` made of an operator `Backup` whose Job failed (`Complete` with reason `JobFailed`) has no dump, so its RestoreJob now fails instead of restoring another run's dump. Stacked on #5223 and targets its branch until that merges, only the last three commits belong here. Checked on a test cluster with mariadb-operator 25.10.2. An operator `Restore` of an older `Backup` with `targetRecoveryTime` set to its dump timestamp restored exactly that dump (`obtained target backup` names it and a row inserted after it is absent from the target), the same `Restore` without the target restored the newest one. Against the real bucket and operator `Backup`s the recording probe attributed to each `Backup` the dump its backup pod logged, the existence check passed for those dumps and refused a pruned one, legacy `Backup`s with a provable dump got pinned while back-to-back runs fell back with the warning, and the two failed runs on that cluster were refused. The controller itself was not run on the cluster, only its code driven by a test against the real bucket. Fixes #5196 ### Screenshots Not a UI change. ### Downstream repositories The diff is confined to the backup controller's Go code. It changes no CRD or API type (`driverMetadata` is an opaque map), no chart, values, package layout or `hack/` script, so no entry of the trigger map applies. - [x] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note fix(mariadb): a RestoreJob now restores the dump of the Backup it names instead of the newest dump of the application. It fails with a clear message when that dump no longer exists in storage, or when the Backup was made of a failed backup run. Backups taken before this release are restored by the one dump that can be matched to them, or else, as before, by the newest dump, with a BestEffortDump warning event on the RestoreJob. ```   ## Summary by CodeRabbit * **New Features** * MariaDB backups now record the selected dump’s filename and timestamp, allowing restores to target the corresponding recovery time. * For older backups without dump metadata, restores use a uniquely matched dump when possible or fall back to the latest dump with a warning. * Restore processing verifies recorded dumps, retries temporary storage checks, and reports failures for invalid or missing recorded dumps. * **Bug Fixes** * Deleting a MariaDB backup now removes its associated dump and operator backup when ownership is verified and no restore is active. Cleanup avoids deleting artifacts when it cannot safely identify them.
