[PVE-User] PBS - Verification, Garbage Collection etc. - best practices?

[Hermann Himmelbauer]

Dear Proxmox / PBS users,
I have the following scenario:

- One Proxmox cluster that backups to PBS server "A" (daily)
- An offsite Proxmox host that backups to an offsite PBS server "B" (daily)
- A daily sync job that syncs the backups from the first PBS server to 
the offsite server

This works so far. What I now wonder is, how to do garbage collection, 
verification, Pruning jobs etc. Are there any recommendations, or some 
other "best practices"?

My vague initial idea would be:

- Set some retention on PBS "A" and do garbage collection / pruning 
daily, at times when the backup and PBS A->B syncing does not run
- Set the sync from A->B in a way that vanished backups are not deleted 
(so that in a case that a hacker deletes backups on Server A they are 
not deleted on B).
- Set a longer retention on PBS "B" than on "A" and do garbage 
collection / pruning daily, at times when the backup and PBS A-> B 
syncing does not run
- Do verification somewhere in between

Any ideas on this plan?

Best Regards,
Hermann
