[libvirt-users] Incremental Backups

[Davide Guerri]

Hi Thomas,
I'm using this script which leverages external snapshots and blockpull: https://github.com/dguerri/LibVirtKvm-scripts

It's very simple and on ubuntu requires some tweaks on apparmour configuration.

Hth

Cheers,
 Davide

Unlike drive-mirror, the new file will include the source disk's content at the time the backup job was started. Atomic backup of multiple disks is supported using the "transaction" QMP command.
