Have you ever thought about snapshots? For a while we used a setup like this: a) a local script is run as ClientRunBeforeJob by the bacula-fd on Dom0 b) this script creates a snapshot for each DomU, mounts it and rsync's it to an attached ide-disk (just one plain disk) mounted somewhere in Dom0 c) the fileset associated with this job only contains /var/xen_backup/ (the mounted extra-disk; it contains a subfolder for each DomU - name taken from logical volume name) I am well aware that this kind of setup is kinda tautologous, but i definatly don't want bacula to backup directly from mounted snapshots. Thats why I do the rather fast rsync first, remove the snapshots and finally let bacula backup from the plain ide-disk. There's only one major drawback: if you back of lots of DomU's with lots of files, you will have them all in one single backup job...which might increase restore times slightly.. ;) BUT: if you choose to work with snapshots, make sure your DomU has at least 200-256 mb ram. Snapshots are still somewhat experimental and sometimes (e.g. with ~128MB ram) cause the running DomU to detect an fs error and remount its root filesystem read-only! -- Mit freundlichen Gruessen / with kind regards Rudolph Bott ------------------------------------------------------------------- Megabit Informationstechnik GmbH Karstr.25 41068 Moenchengladbach Tel: 02161/308980 [EMAIL PROTECTED] http://megabit.net ------------------------------------------------------------------- ------------------------------------------------------------------------- Take Surveys.
