[sheepdog-users] About snapshots

[Ing. Luca Lazzeroni - Trend Servizi Srl]

Hi,
I'm trying to use external snapshot feature of QEMU/libVirt with sheepdog baked vdi to take VDI live backups without using sheepdog snapshots.
This is to avoid the problem of disk-space unreleased on snapshot deletion.

The main problem is that virsh seems to fail to create external snapshot (baked on qcow2 files on local server filesystem) on vm running within sheepdog, probably due to qemu inability to create disk-mirror across the 2 storage technologies (sheepdog / local fs).

Is anyone trying to do this ? Or is this the wrong way to take full backups ?

Thank you all,
