When attempting multiple roll backs upgrades and rollbacks, the IBU resource can sometimes get stuck with this error:

failed to cleanup backups. Perform cleanup manually then add 'lca.openshift.io/manualCleanupDone' annotation to ibu CR to transition back to Idle

This message implies that only backup resources need to be removed but it should also include deletebackuprequests.

If only backup resources are removed, this message will continue to display anytime you rollback

4.15.1

failed to cleanup backups message displays every time rolling back even after removing backup resources

Message also includes deletebackuprequests so the error does not keep occurring
