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

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

[Hermann Himmelbauer]

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.

since proxmox gui/scheduling won't allow serialization of this tasks,
i'm running them via cron/script

# proxmox-backup-manager verify pve-t620_backup --ignore-verified true
--outdated-after 30
# pvesm prune-backups pbs_pve-t620_backup --keep-daily 31 --keep-weekly
8 --keep-monthly 6
# proxmox-backup-manager garbage-collection start pve-t620_backup

regards
Roland
