Alright, now here's one I still can't figure out exactly. How to reduce the size of the repo by directly editying a BackupCopys job retention period.
1) BackupCopy Job as 4 week retention set. 2 weekly Synthetic full points are available besides the normal chain vbk and vib's.
2) Repo starts to get over filled, (decision that these retentions are not really needed for this particular job/VM's) BackupCopy job Retention settings are removed.
3) If you manually restart the job, the retention jobs still show up under the Disk -> Job -> properties.
I was on call with a support rep, and we had to manually remove the .vbk files, this freed up space, but neither re-scanning the repo, or manually restarting the BackupCopy job would remove these point from the Disk -> Job -> properties.
I'm not really a fan of that considering the following scenario:
In a multi admin company I change retention periods. However the Disk properties for available points still shows those old weekly periods, but one would never be able to actually use them since they actually don't exist.
