backing up a vm should be no different than backing up any other server. there are many alternatives for backing up a system. rsync to a remote host, bacula, amanda, crashplan, compilation of self built shell scripts. how to do backups for vms was brought up several times over the several months i was on the xen-users mailing list. it seemed the general good advice is to do a backup from within the vm just like you would any other server. many wanted to use something like lvm snapshots to do full filesystem backups while the vm is running. the problem is that when you take the lvm snapshot, you are taking a snapshot of a currently mounted filesystem which may or may not have problems with it. it will work for vms that have a low volume of writes but something like a database would be a bad thing. one backup strategy i saw at a previous job, and like, was to rsync / (excluding /dev, /proc, /sys, /tmp, etc) to a rsync server and then use hard links on the rsync server to create a rolling snapshots of what the filesystem looked like. i don't have access to the scripts and config for that backup system but this link describes something similar. http://www.mikerubel.org/computers/rsync_snapshots/ of course, there are many many other options depending on what you want to do. hope that helps. mike /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
