[PVE-User] Proxmox PBS: Recommended task schedules (Prune, GC, Verifiy)?

[Mark Schouten]

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.

>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?

>P.S.: I think it would be a great addition to the manual to put some recommendations / best practices there.
