We have a fas2020 and we use it on our Proxmox cluster as a NFS server for
storing VM images(KVM/raw format). For backups, we rely on hourly snapshots
(while the VMS are running) we did test running a VM (debian with
apache/php/mysql) with its hourly snapshot and it worked fine (but I would not
validate this for a critical/high transaction database...).
We do manual coherent backup by stopping the VM, creating a manual snapshot then
starting the VM (less than a minute). Of course, you've got to manually manage
If someone tried and compared the perfs of a VM running with its image on NFS
and then on ISCSI (with a Netapp) I'd like to hear about the results.
