Verify Job Parameters

[franconovik]

Hello,
I am using Proxmox Backup server since 2 weeks.
I configured a Verification Job and it takes a lot of time to complete.
I have daily backups of disks 2 disks of 150GB and other 6 disks of 70GB.
For each disk I keep 7 copies.
I noticed that the Verification Job verifies all the backups and not only the last backup of each disk.
So I am wondering what are the meaning of the parameters :

Max Depth
Skip Verified
Re-Verify After

I wish that the job verifies only the last backup otherwise takes too much time. Can it be done ?

Hi,
if you set the skip verified flag, only backup snapshots which have not been already verified will be verified again. Setting this is in general a good idea. Further, by setting re-verify after snapshots which have already been verified are verified again after the given time-span. This is to detect for possible silent data corruption of the underlying storage.
Max depth only comes into play if you have namespaces, as it tells the job to consider only snapshots found within the given max nesting level.

If you really want to only verify the last backup, you can either manually verify it or set the verify new snapshots flag in the datastore options. By this the snapshots are verified immediately after the backup run finished.
