Hi Thomas,
Hello Davide.
I'm using this script which leverages external snapshots and blockpull: https://github.com/dguerri/LibVirtKvm-scripts
Yeah. I saw that and tried this already. But it needs to be adjusted to libvirtd-1.1.2 i think. Can you do this? I fiddled a litte bit around but wasn't realy successfull. hn LibVirtKvm-scripts # ./fi-backup.sh -b /opt/virt-backup-local/ -d serve.lordcritical [DEB] qemu-img version '1.6.0' is supported [DEB] KVM version '1.6.0,' is supported [DEB] Snapshot for domain 'serve.lordcritical' requested [DEB] Using timestamp '20130920-151742' [DEB] Snapshotting block devices for 'serve.lordcritical' using suffix 'bimg-20130920-151742' [VER] Snapshot for block devices of 'serve.lordcritical' successful [ERR] Error getting backing file for '/var/lib/libvirt/images/serve.lordcritical.bimg-20130920-151742'. At the moment i try: https://bitbucket.org/guilhemfr/virt-back cheers t.
It's very simple and on ubuntu requires some tweaks on apparmour configuration.
Hth
Cheers, Davide

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 thomas
