No snapshots in backups ?

[Walrus]

Hello everyone

We are looking at our overall backup strategy with Proxmox. Although the backup feature seems to work very well, it looks like the vzdump that the Proxmox backup system uses doesn't have any options to include the snapshots, that we might like to keep in our case (of course with KVM and qcow2 instances). I know it's not bulletproof (we have other strategy to backup data from inside our VMs, or prepare for disaster recovery), but keeping the snapshots is needed in some cases.

And this seems quite "official"...
http://pve.proxmox.com/wiki/Live_Snapshots#Backup
"If you want to (live) backup a VM containing snapshots you need at least Proxmox VE 2.3. Please note, snapshots are not included in the backup - see backup logs."

I searched quite a bit on how could we include snapshots in our backups if needed. Anybody has an idea on what should be the best strategy right now to do this within (or outside) Proxmox ?

Thank you !

It just doesn't support it. If you restore a backup, the os will have in effect 'crashed' at the point that the backup occured.

The only way to do something like this would be to have the OS hibernate to disk, perform a backup, then wake and resume from disk.
