Re: [Xen-users] About tape drive.

If you're going that route, I recommend "rsnapshot" or plain old
"rsync". If you're clever, you can do it to the LVM snapshot and speed
the heck out of the process, because most of the files are already there!

Ah! So snapshot the guest, then update the snapshot every so often with an rsync from the guest?.
Use the LVM snapshot to creatae a local filesystem snapshot on Dom0. This can be done via rsnapshot cleanly, and incremental rsync based snapshots can be done regularly to a related rsnapshot repository.

Whilst we're on the subject my personal favourite backup system is rdiff-backup, which provides compressed, diff-based backups of a filesystem - either locally, or over SSH - and provides "time-travel" capabilities for getting old versions of files.
I find rsnapshot friendly. rsync.net is providing commercial support for it.
