[PVE-User] Timeouts while creating backups on PBS

[Sven]

Hello

we have several clusters (~250 VMs) attached to one PBS and run daily 
backups. Each day, there are random timeouts causing some backups to 
fail.

I've disabled the instant verification process to reduce IO-load on the 
PBS during that time. The timeouts are gone since then.

Because we do want to have verified backups, we tried out scheduled 
verification tasks. Then we have the problem, that it takes to long 
(>1d) to verify all ~250 new snapshots sequentially. 50 parallel verify 
jobs works well.

My current idea is to write a custom scheduler to make sure that there 
is a custom amount of verify jobs simultaneously when no backups are 
running.

Is there a better way I don't see? If I may place a feature request: It 
would be nice to be able to specify how many verify jobs can work 
simultaneously.

Thanks!
Sven
