Backup concurrency within one VM with multiple disks
-
Hello,
Is it possible to set concurrency for backing up the individual disks within one VM?
I have set concurrency for backup jobs to 1 but disks within each job are still transferred in parallel.Example:
Create delta backup once every hour :
The VM has 4 disks assigned and all disks are transferred in parallel, which is eating up unnecessary I/O. The remote storage for the backups is using spinning disks, so concurrent I/O is not optimal.

IIRC, concurrency is indeed per VM, not VM disks. Pinging @julien-f

It would be awesome if this could be addressed in a future release

Yes, the concurrency setting is per VMs, not per disks.
It's not planned, but I'm keeping it in mind for the current rewrite, maybe we'll be able to expose this.
