SUMMARY: Backups - Sun and Ultrix Systems

Thanks to all the netlanders for the responses.  It seems the
solution was fairly simple, although no one gave me the exact
answer.  Most of you responded to use the 'o' option, which to
an Ultrix system means "other" than Ultrix.  This option is only
available with the "rdump" command, which unlike Sun systems, is
a different command on Ultrix.  Dump and rdump are the same
executable on Sun systems. (rdump is a link to dump).  This, in
reality, turned out to be the key.  The rdump command, without the
'o' option works just fine, so I can send the same command to both
the Ultrix and Unix systems.

1. Backups - Sun and Ultrix Systems

Hello All,

We use a system of scripts and Exabyte-8200 tape drives to back
up our 50+ Megs of disks here.  The scripts basically do a "rsh
system /etc/dump 0f system:/dev/nrst0 /filesystem" to pick up
file systems from remote machines.  This works very well with our
Sun systems, however when it comes to our DEC/Ultrix systems, we
always get errors something like this:

The Ultrix system bundles the dump up like a huge file, and when
it gets to the Sun host that issued the dump request, an fopen error
occurs.  This is a part of the dump log:

DUMP: Date of this level 9 dump: Mon Nov 12 23:35:21 1990
  DUMP: Date of last level 8 dump: Thu Sep 27 08:34:42 1990
  DUMP: Dumping /dev/rra1h (/mnt1) to sugar:/dev/nrst0
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]

  DUMP: Estimated 298770432 bytes output to file named sugar:/dev/nrst0

  DUMP: fopen on /dev/tty fails
  DUMP: Child 10565 returns LOB status 4
  DUMP: Bad return code from dump: 0

Has anyone out there seen this, and found a resolution ??

Thanks in advance,
