Hm, sounds feasible, although not really secure. Maybe it's not a concern in a switched network where nobody is supposed to know about ARP spoofing and stuff, but if you have a few CPU cycles to spare you could put the backup account's SSH pubkey on machine1, so you can log in w/o password and then run ssh machine1 "tar -jcf - /whereever" >backup.tar.bz2 on the backup machine. Or, if you don't mind some configuring, use amanda. It scales nicely to more machines should the need arise. cheers! Matthias -- I prefer encrypted and signed messages.
