If you rip the LVM disk images to a file backuppc will just backup the changes as that's how rsync works, however this requires you to the storage to image the disk to a working location. Your other option if you are looking for disaster recovery is something like DRDB and a live snapshot of the VMs to a remote location. This is not backup as the remote image is updated live so make a change and it's replicated to the remote location very quickly, but it is a DR option. -- Tim Fletcher<[email protected]> ------------------------------------------------------------------------------ For Developers, A Lot Can Happen In A Second.
