Fellow Gurus -
Earlier today I posted:

==> I am receiving the same message about a tape drive on another machine.
==> Needless to say, deleting and recreating the tape device will not help
==> me. I am trying to use rdump to backup my 4.0 secure NIS server to an
==> 8mm exabyte tape drive on a SunOS Sparc 2 running 4.1.3. I receive the
==> following error.
==>
==> rdump: Date of this level 0 dump: Tue May 12 09:10:47 1998 EDT
==> rdump: Date of last level 0 dump: the start of the epoch
==> rdump: Dumping /dev/rrz2g (/patran_tmp) to /dev/nrst8 on host jefferson.afit.af.mil
==> rdump: Mapping (Pass I) [regular files]
==> rdump: Mapping (Pass II) [directories]
==> rdump: Remote system is not known to be compatible for magtape functions, output being treated as regular file
==> rdump: Estimate: 2077204 tape blocks on disk
==>
==> The available blocks(112148),is less than the estimated blocks(2077204)
==> ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
==>
==> Dump is being aborted
==> rdump: SIGTERM received
==> rdump: The ENTIRE dump is aborted
==>
==> Needless to say, this makes it hard to do my backups since the 8mm is the
==> only tape drive I have. Has anyone else run into this problem and fixed
==> it?
==>
==> I also never had the message
==>
==> rdump: Remote system is not known to be compatible for magtape functions, output being treated as regular file
==>
==> until I upgraded to 4.0x.
==>
==> I have not had a chance to install any patches on this machine or the other
==> machines in my 4.0 secure NIS domain. Will that help? I have gone 3 months
==> not being able to backup these machines. Buying a tape drive specifically
==> for this one domain is not an option, we must buy what will service all
==> the domains that I administer.
==>
==> Thank you.

The only replies I received were from Tom Leitner in Graz, Austria. He
suggested:
Why don't you just use vdump to dump the Digital Unix machine to the
remote Sun tape? Something like this:
vdump -v -u -0 -F 64 -b 60 -f - /usr | rsh remote-host dd ibs=60k obs=60k
of=/dev/nrst8
Tom
and
Another alternative is Gnu-Tar, alias gtar. I have it on all machines.
You can use something like:
gtar cvf remote-machine:remote-tape /home
without problems.
Tar is the perfect format for you as you can read the resulting tape
on virtually any Unix system around :-)
Let me know if you need the binary or the sources (ftp.gnu.org).

Before we have the paperless office, we have the paperless toilet!
After 10+ years I did not think of either because I had gotten into a rut.
Neither will be adequate for me. I filched a tape drive from another
department and will use it to do backups locally. The dump on the
SUN machines software for the rdump/rmt can not talk with the rdump/rmt
on the DEC. Oh well, live and learn something new each day :-)
