fix(clickhouse): restore the archive a Backup was taken as by myasnikovdaniil · Pull Request #5208 · cozystack/cozystack

What this PR does

A ClickHouse RestoreJob restored the newest archive under the app prefix, whichever Backup it named. Strategy pod generated the archive name with date -u and nothing was recorded on the Backup, so restore could only list the remote archives and take the last one. Restoring an older Backup brought back the latest data.

Now the controller names the archive before it creates the backup Job (clickhouse-<app>-<startedAt> from persisted status.startedAt, so retried pods write the same one), passes it to the pod as .ArchiveName and records it in the Backup driverMetadata. Restore takes exactly that archive and fails with its name when storage has no such archive. The name is recorded only when the Job's pod got it, so a Job left from the previous controller during an upgrade, or a custom strategy with its own names, leaves no name instead of a wrong one.

A retried pod reuses the name, so it waits for an attempt the sidecar still runs (no 423) and asks for resume.

A Backup outlives its BackupJob and a Plan names BackupJobs after the schedule slot, so a BackupJob created again under a used name met the earlier run's Backup when its Job completed, took it as its result and left the archive it just wrote recorded nowhere. Now it fails if that Backup records another archive, and the message names both. A retry of the same run still gets its own Backup back.

Old Backups have no recorded name and stay restorable: the pod logs a WARNING and takes the newest archive stamped no later than takenAt, and fails when nothing qualifies. While the chart rolls out, previous controller pod can still render the new template and pass no takenAt, so a restore of a Backup without recorded name fails before it touches any table, and works when created again after the rollout.

Fixes #5199

Tests are go unit tests for naming, recording, a reused BackupJob name and restore render, and hack/altinity-backup-strategy.bats, which runs the shipped script against a stubbed clickhouse-backup API (the restore tests go red on the old template). Checked on a live ClickHouse with two backups of 1500 and 2000 rows: restore of the older one by recorded name ends with 1500 rows, fallback for an unnamed older backup picks the same archive with the warning, a missing archive fails without touching the table, a retry over an existing local backup completes under the same name. The controller binary itself was not run on the cluster, only its rendered output in the pod.

Release note

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.

Summary by CodeRabbit

New Features
- Backups now use a consistent archive name tied to the backup job, and completed backups retain that name for future restores.
- Restores can select the recorded archive and backup timestamp. If no archive was recorded, the system selects the newest eligible archive for the application.
Bug Fixes
- A restore now fails when its recorded archive is missing instead of silently selecting a different one.
- Backup requests avoid starting a duplicate action when the matching action is already in progress.

The Altinity strategy named each archive inside its Pod with date -u and recorded nothing on the Backup, so a restore could only guess: it listed the remote archives under the application's prefix and took the newest. A RestoreJob of an older Backup therefore restored whichever backup had run last. The controller now names the archive before it creates the backup Job, from the BackupJob's persisted StartedAt, so every reconcile and every retried Pod of the Job writes the same one. The name is recorded in the Backup's driverMetadata next to the strategy parameters, and a restore renders it into the strategy Pod, which restores exactly that archive and fails, naming it, when remote storage no longer holds it. The name is recorded only when the Job's Pod was given it, so a Job created by an earlier controller, or a strategy that names its own archives, leaves the Backup without one instead of pointing it at an archive that does not exist. Because a retried Pod reuses the name, it waits on an attempt the sidecar is still running instead of being refused with 423, and asks for resume, so a local or partial remote backup an earlier attempt left is completed rather than refused as existing. Backups taken before names were recorded stay restorable: the Pod picks the newest archive whose name is stamped no later than the Backup's takenAt, which is set only after the backup Job finished, and logs a warning that the choice is a best effort.

Walkthrough

The controller now passes archive names and backup timestamps to the Altinity strategy and stores archive names in Backup metadata. The strategy uses that metadata for restore selection and handles backup creation retries. Tests cover controller rendering and strategy behavior.

Changes: Altinity archive selection

Layer / File(s)	Summary
Controller archive identity and metadata `internal/backupcontroller/altinitystrategy_controller.go`, `internal/backupcontroller/altinitystrategy_controller_test.go`	The controller derives archive names from `StartedAt`, passes archive names and timestamps to templates, and records the name when the completed Job contains it. Restore rendering receives the stored archive name or an empty value. Controller tests cover these cases.
Strategy archive selection and retry behavior `packages/system/backupstrategy-controller/templates/strategy-altinity-default.yaml`, `hack/altinity-backup-strategy.bats`	The strategy uses the supplied archive name for backup creation and exact-name restore. If no name is recorded, restore selects the newest qualifying archive no later than `takenAt`, or fails if none matches. Backup creation waits for a matching in-progress action and resumes a failed action. Bats tests cover these paths and render validation.

Merge Risk: Low · up to d7ae3

The change makes ClickHouse restores use the archive a Backup was taken as, which is the intended fix. A few edge cases remain: two backups starting in the same second, restoring legacy Backups during a controller upgrade or rollback, and a same-name Backup collision where no archive is recorded. They are bounded and worth follow-up, but they do not block the main path.

Full details: Title check

Explanation

The title "fix(clickhouse): restore the archive a Backup was taken as" matches the main change. The PR makes Altinity backups record a deterministic archive name, and restores use the archive recorded on the Backup instead of the newest matching remote archive. The title states the fix and its scope (ClickHouse). It also fits the linked issue #5199, which asks that a RestoreJob restore the archive belonging to the referenced Backup.

Full details: Linked Issues check

Explanation

Issue [#5199] requires RestoreJob to restore the archive for the Backup in backupRef, or fail without restoring another archive. The controller derives a stable archive name from persisted StartedAt, passes it to the backup pod, and records it only when the Job pod carries that name. The restore template checks remote storage for the recorded name and restores only that name. It fails with the name when the archive is absent. The template also provides a documented best-effort fallback for older Backups that have no recorded name. The added Go and Bats tests cover naming, metadata recording, exact restore selection, missing-archive failure, fallback selection, and retry behavior.

Full details: Out of Scope Changes check

Explanation

The changed controller code, Altinity strategy template, Go tests, and Bats tests all support issue [#5199]. The controller changes implement deterministic archive naming and metadata propagation. The template changes implement exact restore selection, missing-archive failure, legacy fallback, and retry handling. The tests verify these behaviors against rendered strategy output and a stubbed API. No unrelated change is demonstrated.

Make archive names unique per BackupJob, not per UTC second.

Two BackupJobs for one application that start in the same UTC second get the same archive name. The second backup Pod may attach to the first archive's in-progress action, so both Backups can record one archive. Include a per-job value, such as the BackupJob name, in altinityArchiveName, or serialize Altinity BackupJobs per application.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

A previous successful create action is treated like a failed or absent action: the retried Pod sends another create_remote for the same completed archive.

The retry can fail on an existing archive or unnecessarily re-create it, turning a completed backup into a failed or altered one.

This can occur when: A Pod is retried after the sidecar completed its create but before the Pod or Kubernetes Job recorded success.

Test gap: the retry fixture covers an in-progress action but not an already successful create. An implementation that always re-POSTs completed archives passes this test.

The tests do not detect the duplicate-create failure or overwrite risk on that retry path.

This can occur when: A retry begins after the earlier create action reached success.

altinityJobCarriesArchive treats the archive name appearing anywhere in the serialized Pod spec as proof that the backup command used it. An unrelated annotation, environment variable, or unused argument could make the controller record an archive the Job did not write.

A subsequent restore looks for the recorded, nonexistent archive and fails instead of selecting the archive the Job wrote.

This can occur when: A customized or older strategy includes the generated name in its Pod spec but creates an archive under its own name.

Keep legacy restores working when .Backup.TakenAt is missing.

During a controller upgrade or rollback, an older controller can render this restore template without TakenAt. The default then sets the cutoff to empty. The jq filter matches no archive, so restores of Backups without an archive name exit 1 even when their archive exists.

Do not derive a legacy restore cutoff from a Pod-generated archive name.

For a Backup without an archive name, the restore filters remote archives with name <= takenAt. The archive stamp comes from the backup Pod clock. takenAt comes from the controller clock. If the Pod clock runs ahead by more than the backup duration, the only archive is excluded, and the restore fails with "no archive". Rely on a persisted archive name for restores, or record a timestamp from one clock source.

Every test in hack/altinity-backup-strategy.bats made a directory with mktemp -d and never removed it, so each passing run of the file left nine directories in TMPDIR, and they pile up on any machine that keeps it between runs. Each test now removes its directory as its last statement. A failed assertion aborts the body before that line, so a failing test keeps its stub log and rendered script for inspection. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

A Backup outlives the BackupJob that made it, so a BackupJob created again under a name already used meets the earlier run's Backup when its own Job completes. That happens by hand, and from a Plan reconciled again inside its starting deadline, since a Plan names each BackupJob after its schedule slot. The Altinity driver took the earlier Backup as its result: the BackupJob turned Succeeded with a BackupRef recording the earlier run's archive, the archive this run wrote was recorded on nothing, and restoring what the BackupJob reported brought back the older data. An existing Backup is now taken as this run's only when it records this run's archive, which is what an earlier reconcile of the same run leaves when its status write is lost. Any other fails the BackupJob, naming both archives, and leaves the earlier Backup untouched. Assisted-by: LLM Signed-off-by: Myasnikov Daniil <[email protected]>

Reject an existing Backup when neither side records an archive.

When the Job does not carry the archive name, reconcileAltinity sets archive to "". A Backup without archive metadata also yields got == "". The check at line 515 then accepts that Backup. The BackupJob is marked Succeeded and its BackupRef points to a Backup that this run did not write. This affects Backups created before this change, and Backups from strategies that do not render .ArchiveName.

Before this PR, the AlreadyExists branch also adopted the existing Backup. This path is therefore not a regression. The new check still does not enforce its stated rule, which is to accept an existing Backup only when it records this run's archive.

A fix must separate a collision from a retry. If an earlier reconcile created the Backup but did not persist BackupRef, the retry sees the same empty archive. A rule that rejects every empty match would fail that retry. Use a persisted identity that binds the Backup to this BackupJob, such as an owner reference or a label checked before adoption. The Backup created here has no such identity today.

Verdict: LGTM

Reviewed the diff and ran the shipped hack/altinity-backup-strategy.bats plus the internal/backupcontroller Go tests on a clean checkout; both green, and the bats restore cases go red on the old template, so they exercise the regression rather than a happy path.

Checked the parts most likely to bite:

altinityArchiveName is minted from Status.StartedAt, which is persisted before the Job is created and guarded against rewrite, so the name is stable across reconciles and Pod retries.
altinityJobCarriesArchive distinguishes a Job rendered from the new template (full archive literal present) from an old or foreign one (no literal timestamp at render time), so it will not record a name the Pod never used.
The reuse guard fails the BackupJob on a name collision with a different recorded archive instead of mis-pointing the Backup.
Both upgrade directions degrade to the best-effort takenAt fallback, never to a silently wrong archive.

Non-blocking:

The resume path sends create_remote?...&resume=true on every backup and reads /backup/actions with endswith(command); both assume a clickhouse-backup HTTP contract only exercised here against the in-repo stub. A wrong endswith degrades to a retry behind the 423 path, so it is not a data-loss risk, but the real tool's command-string format is worth confirming once.
The recorded-archive restore path checks presence but does not apply the broken exclusion the fallback path uses. Defensible, worth a one-line comment.

## What this PR does A ClickHouse `RestoreJob` restored the newest archive under the app prefix, whichever `Backup` it named. Strategy pod generated the archive name with `date -u` and nothing was recorded on the `Backup`, so restore could only list the remote archives and take the last one. Restoring an older `Backup` brought back the latest data. Now the controller names the archive before it creates the backup Job (`clickhouse-<app>-<startedAt>` from persisted `status.startedAt`, so retried pods write the same one), passes it to the pod as `.ArchiveName` and records it in the `Backup` `driverMetadata`. Restore takes exactly that archive and fails with its name when storage has no such archive. The name is recorded only when the Job's pod got it, so a Job left from the previous controller during an upgrade, or a custom strategy with its own names, leaves no name instead of a wrong one. A retried pod reuses the name, so it waits for an attempt the sidecar still runs (no 423) and asks for `resume`. A `Backup` outlives its `BackupJob` and a Plan names `BackupJob`s after the schedule slot, so a `BackupJob` created again under a used name met the earlier run's `Backup` when its Job completed, took it as its result and left the archive it just wrote recorded nowhere. Now it fails if that `Backup` records another archive, and the message names both. A retry of the same run still gets its own `Backup` back. Old `Backup`s have no recorded name and stay restorable: the pod logs a `WARNING` and takes the newest archive stamped no later than `takenAt`, and fails when nothing qualifies. While the chart rolls out, previous controller pod can still render the new template and pass no `takenAt`, so a restore of a `Backup` without recorded name fails before it touches any table, and works when created again after the rollout. Fixes #5199 Tests are go unit tests for naming, recording, a reused `BackupJob` name and restore render, and `hack/altinity-backup-strategy.bats`, which runs the shipped script against a stubbed clickhouse-backup API (the restore tests go red on the old template). Checked on a live ClickHouse with two backups of 1500 and 2000 rows: restore of the older one by recorded name ends with 1500 rows, fallback for an unnamed older backup picks the same archive with the warning, a missing archive fails without touching the table, a retry over an existing local backup completes under the same name. The controller binary itself was not run on the cluster, only its rendered output in the pod. ### Downstream repositories - [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(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. ```   ## Summary by CodeRabbit * **New Features** * Backups now use a consistent archive name tied to the backup job, and completed backups retain that name for future restores. * Restores can select the recorded archive and backup timestamp. If no archive was recorded, the system selects the newest eligible archive for the application. * **Bug Fixes** * A restore now fails when its recorded archive is missing instead of silently selecting a different one. * Backup requests avoid starting a duplicate action when the matching action is already in progress.

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. ```

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

v1.7.1 is a patch release made of backported fixes, so a "Features and Improvements" section misdescribes it. Its four entries move to Fixes, and the ClickHouse BackupJob name-reuse note joins the other #5208 entry instead of sharing one with #5211.
