Hello,

After migrating to Proxmox 4, I stumbled onto the fact that it isn't possible to backup LXC with snapshots on LVM.
As my VM are often quite big in size (50-100G), freezing the containers during backup isn't possible for me.

What would be the best practice to backup those containers ?
I don't need to save the state (RAM) of the machine, would just copying the .raw disk as well as the .conf be good enough as a backup (It works, but I don't know if issues can occurs doing it this way) ?

Thanks.
 
Sadly that isn't possible for me, as I can't afford a 30mn downtime just to create a backup.

Would copying the .raw file create issue while restoring those file ?
 
Not to hijack the thread but I have a question about the "stop" method for LXC backups. I don't mind the brief downtime so I was thinking of going this route but the "stop" concerns me. Is it really a "stop" AKA pull the power cord out? Or is it more like "shutdown" AKA graceful?
