I have a backup job for all of my VM. The job is configured with primary snapshot that maintains 10 snapshots. I ain an auxiliary SnapVault copy to a second bay. The snapshots I retain 30 plus every month for a year. The backup works correctly and replication.
The data aging is not working and the snapshots are not deleted on the source volume as they are locked by an owner.
CLUNETPROD::> snapmirror snapshot-owner show -vserver SVM_NFS -volume VOL_NFS_DATASTORE5
Have a look one of the volumes in OCUM and click on the protection tab, I suspect that there is a protection relationship been created every time the volume is backed up which is why it can't age out the snapshot. Can't explain why that would be happening or how to stop it sorry but would explain why data aging is not working.
