What is wrong with WBAK/RBAK for doing dumps; we use it all the time with the
APOLLO 6250 tape drive and it works fine.  What is the problem with links to
which you refer.

I certainly hope APOLLO never supports the 4.2BSD DUMP program.  That program
requires an idle file system (typically making you to take the system down and
run single user) to get a guaranteed good dump of the disk; WBAK has no such
problems.  In our SUN network, we have to keep a spare eagle around and in the
middle of the night we transfer file systems from other machines to the spare.
Then we backup the now-idle spare disk.  That's incredibly painful compared to
just running a backup over the network with WBAK.

It's also very nice that you use the same program for system dumps as you would
to write a simple tape to send to another site.
