I just have to say this:
"Crash-Consistent Backups"
If you dd, cat, dump, or skip-to-my-Lou the disk you're running on,
you won't likely get a good result. You certainly won't get a
*reliable* result, and unless you have a spare drive sitting around, you
won't know till you're screwed.
I don't know whether the network stack will fit on boot floppy, but I
do have a rather dim memory that the UNIX PC has a backup tool. I'd be
looking at that.

Don't you have rexec or rsh on the system to just pipe the dd output
trough to the remote machine? Something like
being on your AT&T
dd if=/dev/diskdevice | rsh modern-unix-host dd of=diskimage
or the other way round - being on your modern-unix System:
rsh old-unix-host dd if=/dev/diskdevice | dd of="diskimage"
instead of "dd of..." "cat" might also work What I was thinking of was squirting
'/dev/rawdisk' somehow out the
ethernet.
Ahhhh, I hadn't thought of that, but of course that seems like an
ideal solution. I wonder if I can get 'netcat' to work... Or just dd
in small blocks of, say, 1MB each, with dd offsets, and FTP the chunks
somewhere.
Anyway, you've given me lots to think about. Thanks!
