[libvirt-users] Incremental Backups

[Thomas Stein]

Hello.

Is someone performing incremental backups via libvirt for qemu/kvm 
machines? I'm still having a hard time to
find a nice procedure. I mean is it possible to make a full backup of an 
image on monday a do the next days of the week
incremental backups?

Another way could be mount the image and rsync its contents. Does that 
makes sense?

Also i read in qemu changelog:

---
Support for a new block device background job. Started by drive-backup, 
it will backup a disk's content to a new file. 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.
---

Is this supported by libvirt?

thanks and best regards
