Data Backup and Recovery Discussions

SnapCenter VMWare Plugin showing old backups

Chandler

A while back we upgraded from SC 4.0 and are now running 4.4 however when we go to restore a VM for example it lists all backups since 2019.  Is there an easy method to purge these?  I'm not seeing the "Cleanup" process in the vCenter SC task logs but I've verified with support through the API that the cron job is configured.  Can the cleanup be ran manually like on the SC server but on the SCV Plugin?  Due to this, selecting a backup for restore takes quite a while due to the size of the backup list.

Update:

I've found that manually changing the API entry under Put Schedules and changing this entry to a manual time for it to run would execute the "Clean secondary backup" job to run:

{

"name": "Schedule-PurgeBackups",

"cronExpression": "0 30 8 ? * SUN *"

}

 

So the example above kicked it off at 8:30am on Sunday.  However, it's not cleaning up due to the following errors:

Update 2:

I've manually deleted a few backups from the vCenter interface and ran the Cleanup job again and that seems to have fixed the issue.  I suppose it kept information from older snaps that were originally on the 4.2 version, prior to the Data Brokers.

The only issue I have now is that there are a few backups that through vCenter don't allow me to Delete since it's greyed out and the SCV doesn't have a record.  A support case could be open to manually delete them.

Update 3:

It appears that the older backups are showing as Mounted and I can't find a way to get their ID to unmount them.  When I select them to unmount, nothing appears in the unmount window.  Is there a way to force show Unmounted in vCenter?
