Multiple pbs server backup, dirty-bitmap status always invalid and cleared

[juliokele]

Hi,

I've two pbs server, one local and one offsite.
On backup the dirty-bitmap status always invalid and cleared.
No VM restart, backup mode: snapshot
Is this a normal behavior?

Backup to Server 1:

Is this a normal behavior?

When you backup to multiple PBSs, yes.

Would suggest to use remote sync: [1] to pull the backups from the local to the remote PBS (and only backup the VMs to the local PBS, of course).
