What happened?

The indexer used by the ScheduledBackup controller to find child Backups doesn't work because it checks Backups for owner references of kind Backup instead of ScheduledBackup:

This check means that the indexer never returns any results and so the GetChildBackups method always returns an empty slice.

Even if it correctly looked for owners of kind ScheduledBackup, it would only work for the cases where the ScheduledBackup is configured with:

backupOwnerReference: self

When backupOwnerReference is set to none (the default) or cluster this indexer will also not return anything.

The intended purpose of the GetChildBackups method that uses the indexer is to prevent concurrent Backups for a ScheduledBackup. The check has never worked and the Backup controller handles concurrency itself by checking for running Backups before starting a new one.

The indexer should be removed.
