Hi,

it seems that LXC (even on latest Proxmox version, 5.1-51) doesn't support snapshot backup but only suspension mode.

How can I avoid this behaviour and the resulting downtime?

Tnx in advance...
 
LXC support snapshot backups, but the underlying storage need to have snapshot capabilities.
 
Yes, I mean that is LXC in combination with NFS storage that will not had snapshot functions...

At this moment I have only 2 nodes and a qnap storage.
I made backup with NFS export from qnap and obviously the LXC containers going to suspension doin' backup...
How can I improve with this scenario to having snapshot?

Export iSCSI from qnap maybe? Or I just need to convert all my LXC to Qemu?

Tnx.
 
You need a storage that supports snapshots (local ZFS, local LVM-thin, ceph). Neither NFS nor iSCSI supports snapshots.
