Hello
We got a ProxmoxVE cluster having 20 nodes and are "trying" to backup all VM's overnight.
Currently it will start 20 backup tasks (1 per node) which will result in very high I/O delays as the destination NAS won't be able to handle the load.
If we limit the bandwith for the backups, some of the backups won't complete after 3 days, not really ideal.
* Are there any best practices for backups having lot of nodes?
* Are there other backup options if we would use ceph-storage?
* Could differential backups (github.com ayufan/pve-patches) be a solution for this case?
Thank you
