Someone must have figured this out by now... Actually, we have a script hacked up to do this without replacing rsh. It goes something like this: #!/bin/sh - ssh-add || exit 1 ssh tapeserver mt rewind || exit 1 blksize=50 for i in / /var /usr /usr1; do dump 0uBbf 2000000 $blksize - $i | ssh tapeserver "team 50k 16 >/dev/nrst0" done ssh tapeserver mt rewind || exit 1 Of course you should have RSA keys set up and installed the 'team' port. The ssh-add will take care of proxying your passphrase. Team is a buffering process, tune the blocksizes for best performance. If the machines are slow you might rebuild sshd with the 'none' encryption type and change the ssh command lines to 'ssh -c none'. Lastly, make sure the dump blocksize and #blocks/tape numbers match your tape drive (ours is for a 2GB drive).
