hmm, okay

well if you want to archive a file system remotely, you can jjust have it
stored as a large file on the remote machine, so umount the fs (so it wont
change while rsync is playing with it. 
rsync -e ssh -v /dev/hda1 backup at remote:/data/backups/weirdfs.img 
or something

this means you get the advantages of rsync at least.

Of course this is probably not what the person wants.
