- *If* you can free up some disk space on the other machine (looks like you
- need about 300Mb) you can NFS mount a directory from the machine with the
- tape drive onto your machine and do a mksysb into it. (If you need details
- you can email me.) You can then, if necessary, dump the image to tape.
- To restore, you can set up the machine with the tape as a network install guy
- and stick the image back on disk. It requires some contortions, but as
- far as I know your only other choices are to hook up a tape drive or to
- backup to floppies. (And if you backup to the 300+ floppies you know that
- somewhere about #50 there's gonna be a bad one.)

- I don't follow. The machine with the tape drive/image is going to have
- to be up. And I don't even want to think about the horrendous contortions
- you'd have to go through if all you have is dump/backup's of the
- individual filesystems. Gack! I'd rather do a mksysb to floppy!
