DFM 5.2 Protection Manager backup retention issue

marks — Thu, 05 Jun 2025 05:28:03 GMT

Does anyone know why 'dfpm backup list' doesn't list all of the backups that are in the snapvault secondary volume that are listed with 'dfpm dataset snapshot list' ?

We discovered this when troubleshooting why snapshots older than the retention periods configured aren't getting deleted. I think that the two are related but I may be interpreting the output incorrectly.

Thanks,

Mark

Here's the information about the protection manager config and the command output I'm seeing:

I have a dataset with Primary and Backup nodes:

The Primary node has 19 volume root qtrees (/vol/volname/-)
The Backup node has a single volume

The protection policy uses a base policy of 'Remote backups only' i.e. Backup primary to secondary without local backups.

The Primary node has no local backup schedule configured
Primary data to Backup has a schedule of Daily @ 0400 Monday>Saturday, Weekly @ 0200 Sunday
The Backup node has backup retention durations set to 6.0 Daily, 5.0 Weekly
