Hi,
Skip the verify. I causes massive IO and has little to no use on ZFS,
which already does checksumming.
Pruning and GC looks like a good interval.

Subject [PVE-User] Proxmox PBS: Recommended task schedules (Prune, GC,
Verifiy)?
Dear Proxmox users,
I am currently configuring a PBS server. For the retention, I used the values
from the following page:
https://pbs.proxmox.com/docs/maintenance.html
keep-last:3, keep-daily:30, keep-weekly: 8, keep-monthly: 11, keep-yearly:9
This looks like a decent retention scenario. The underlying datastore is ZFS,
approx. 40TB.
The backups to my PBS-Server is done at night, starting at 1:00 from a
PVE-Cluster. The backup itself runs for approx. 5 hours.
Working great, o.k. - now I need to configure the following tasks:
- Prune
- Garbage Collection
- Verfiy
Well, it's now really unclear to me when and how often I should do these tasks?
Do I have to ensure in some way that these tasks don't overlap?
Thinking in non-overlapping terms, I'd do it like this:
- Prune: daily at 6:00
- GC: daily at 11:00
- Verify: daily at 15:00
Or is it better to simply do it like that:
- Prune: hourly
- GC: hourly
- Verfiy: hourly
Any hints?
Best Regards,
Hermann
P.S.: I think it would be a great addition to the manual to put some
recommendations / best practices there.
