These directions work great, thanks for sharing them! The ability to move a vserver so easily is wonderful.

I have just one question/comment: Moving a group of vservers with rsync doesn't preserve file unification, so rsyncing a handful of vservers takes a LONG time and consumes a lot of disk space on the server one is rsyncing to, until a vunify run anyway. (I had a 500MB unified vserver that required 2.5GB disk space after moving, for example.)

Any thoughts (or scripts to share) anyone about backing up vservers more efficiently?
