At my workplace I use KVM as our primary virtualization solution with LVM volumes for each virtual hard disk. I have created a simple script to perform an image based backup of a guest using dd. This could be improved by setting a snapshot while the guest is down and then immediately bringing it back up, however, I use backuppc for file based backup of the data on each machine. So, I don’t feel the need to perform image based backups often enough that I can’t fit them in a normal maintenance period.

The script is posted below and at github

Update: I’ve changed this post so it will always include the latest version of the script from github
