I'm also interested in how this can be done. I've got two 486/50 EISA machines
running SVr4.2 on an Ethernet connection. Only one has a tape drive (DAT).
Any suggesions how I can access the tape from the tape-less machine?

how about isomething like

find ..... | cpio -oB | rsh tapehost dd of=/dev/tape

tar cf - * | rash tapehost dd of=/dev/tape

or something similar. Basically create the backup onto a data stream and pipe
that through rsh (remote shell, not restricted shell) into the dd program
which puts that data on tape

There are several ways you can you this, I've heard that RFS has a way of
accessing devices but I haven't really looked at that.

(What follows is a bit BSD'ish and will probably need slight mods for SYSV)

It depends what you want to use to back up the machine, if you are using
cpio or tar or something like that then you can do something like...

[on tapeless machine]

find . -depth -print | cpio -oamdBu | rsh tape_machine dd of=/dev/TAPE bs=5120

[block sizes may be different]

or...

tar cvf - . | rsh tape_machine dd of=......

Restoring is just the same backwards [still on tapeless machine]...

rsh tape_machine dd if=/dev/TAPE bs=5120 | cpio -ivBumd

This assumes that you have your /.rhosts file setup to allow root to rsh
to the machine with the tape drive.

Hope thats some use,

Lee.

Probably best done with 'rdump', if you have that command available.

Or a combination of 'cpio' and 'dd' across the network.
