Do you know if it is possible to image-copy a snapshot off
to another system? A backuppc archive contains so many hardlinks
that normal copy techniques are not practical. I currently
raid-mirror to external firewire drives that are rotated offsite
periodically, but it would probably work better to freeze an
LVM snapshot and copy that instead.
