Yes. You can't restore the root filesystem while you're running from it.
Chaos would ensue. Processes would die, active /dev nodes would be
overwritten, the restore would likely crash halfway through leaving you
with an unbootable system, dogs and cats living together, mass hysteria!

To restore a backup of the root filesystem, you must first boot from
the miniroot on the IRIX 5.3 CD. This assumes of course that you have
a CD-ROM drive on your Indigo2. If you don't have a CD-ROM drive on
the Indigo2 itself, you can still load the miniroot over the network
from another SGI system that does have a CD-ROM drive. Once you have
the miniroot loaded, shell out of 'inst' with the 'sh' command and _then_
restore the backup tape of the root filesystem.

Verify the backup first though. :)

1. tape backup only full restore?

I'm using an SGI Octane running 6.5.4.  I have a Quantum DLT drive
attached to it and just did a full backup.  It did have an option to
back up a file or directory also.  Is there a way to restore single
files with the GUI or does it only do complete restores?  Started the
restore process to see and chickened out half way thru as I hadn't
seen any options to select files off the tape.

If not, and it's possible thru tar or something, any pointers to how
to do that would be greatful.  Never used tar except for anything but
grouping a bunch of files together.

And of course the last one, if there are any GUI programs that won't
cost anything, that would be helpful as well.  Thanks.

Steve
