Hi all,

I had no issues with further version but since I upgraded to 4.x I am facing an issue while running backups

KVM no issue at all

Code:

but the same job on the same backup device is not able to run backups for LXC

Code:

181: Aug 31 20:06:40 INFO: Starting Backup of VM 181 (lxc)181: Aug 31 20:06:40 INFO: status = running

181: Aug 31 20:06:40 INFO: mode failure - storage does not support snapshots

181: Aug 31 20:06:40 INFO: backup mode: suspend 181: Aug 31 20:06:40 INFO: ionice priority: 7

[...]

Backup device is a LVM volume.

This is a big issue for me as it is impackting the SLA while shutting down the VM instead of using snapshot mode...

I don't know why it is failing. Maybe you have an idea.

Thanks,
