[caitlinstrong]

Removing the repo backup schedule from the cluster spec will delete the cronJob(s) associated with the backup schedule.

What is the current behavior (link to any open issues here)?

When a backup has a cron scheduled, for example:

spec:
  backups:
    pgbackrest:
      repos:
      - name: repo1
        schedules:
          full: "0 1 * * 0"
          differential: "0 1 * * 1-6"

Removing the backup schedule from the cluster configuration and applying the changes does not automatically delete the cronJob associated with the backup schedule. The cronJob must be manually deleted for the schedule to be removed.

What is the new behavior (if this is a feature change)?

• Breaking change (fix or feature that would cause existing functionality to change)

To address this issue, I've changed the position of the case statement for the cronJob in the function cleanupRepoResources. With this change, cronJobs are automatically deleted when the repo backup schedule is removed from the cluster spec.
