Backup one VM with multiple disk to multiple datastore or multiple pbs server

[Dark26]

Bonjour,

We want to test a configuration like this :

We have a PVE host, with one big vm ( for nfs share/ or CIFS), running on an external ceph, with 100 To.
We want to use the dirty bitmap for quick backup because it's a lot of small file...

For example, we can have the VM with 4 disk of 25 To, it will be beter if we want to move the storage somewhere else ( better than a disk with 100 To).

For the backup, we can have 2 pbs serveur with 50 To each.

Is-it possible to backup 2 disk to the first pbs server and the other 2 disk to the second pbs ?

Or we can share the storage ( nfs or iscsi or gluster ...) .... of one server to the second, so we can have 2 datastore of 50 To each.

Is-it possible to backup the 4 disk fg 25 To each to the 2 datastore ?

I see the option for no backup for the disk, but it's for all job, that' not what we want.

If you have a solution.

Best regards

no, that's not supported. you could manually switch which disks are backed up in between backup tasks, but then you will lose dirty bitmap support.

i was thinking of a hack like this, but without the dirty bitmap, that's not possible.

Thanks for the quick response.
