Can someone point me to a program to
read 8mm tapes made with the vms
program "backup" on a unix box.

Such things exist on the DECUS CDROMs, although I don't know the name.  You
might try surfing the Acorn Software CDROM Center:

        ftp://flash.acornsw.com/
        gohper://gopher.acornsw.com/
        http://www.acornsw.com/

To see what you can find.

The following article decribes one product for AIX. Contact the vendor
to see if they have a version for your dialect of unix.

Yes, there is.  My company provides a product called Vbackup as part of
its VMS-for-UNIX toolset.  It reads and writes VMS backup tapes and is
also suitable for doing system backups.  When run in conjunction with
our DCL shell (VCL) you can even use VMS style backup commands.

There are two programs that I know of to allow Unix to read VMS backup
save sets:

vmsbackup:

   vmsbackup reads a VMS generated backup tape, converting the files to
   Unix format and writing the files to disk. Reported by the README
   file to run on Ultrix/VAX and Sun. I have a copy running on
   Ultrix/RISC. I also have an mx'd version running on OSF/1.

   Available via anonymous ftp from:

   Host cs.tut.fi

       Location: /pub/src/tape-readers
         DIRECTORY drwxrwxr-x        512  Oct 24 1993  vmsbackup

   Host emx.cc.utexas.edu

       Location: /pub/mnt/source/util
         DIRECTORY drwxr-xr-x        512  Dec 11 1992  vmsbackup

   Host ftp.cc.utexas.edu

       Location: /source/util
         DIRECTORY drwxr-xr-x        512  May 21 1994  vmsbackup

Vbackup:

   A commercial product by Boston Business Computing, Ltd.  According to
   BBC, this product allows you to read and write to VMS save sets on
   your OSF/1 platform.  It is also available on most UNIX platforms.

   In addition, Vbackup performs a full system backup in normal
   multi-user mode.  It stores files portably across VMS and UNIX and
   accesses network tape and disk devices as well as reconstrucing data
   from corrupted media. Vbackup provides a common interface for users
   who are familiar with VMS backup.

   If you would like to receive more information on Vbackup, contact

: Vbackup:

Just to clarify: it's free if you have OSF/1, and available for a fee on other
platforms.

:    as well as reconstrucing data
:    from corrupted media.

For restoring VMS save sets on UNIX, this is probably the most important
distinction between vmsbackup and Vbackup.

vmsbackup sometimes has problems with VMS BACKUP error recovery mechanisms and
can halt on or silently restore corrupted data.  Vbackup never restores
corrupted data without issuing a warning message, and in most cases completely
recovers corrupted data to its original form.

1. Transfer VMS backup saveset from tape to disk

 I only have access to a unix system.
I have an old (1995) Exabyte 8mm tape with some
VMS backup savesets written to it.

My question is:

   How can I copy the saveset files from the tape to
   a unix disk in such a way that the disk-files are fully functional
   (ie I don't trust tape forever, but putting them on disk
   would be great)?  (i.e. they must work with 'vbackup'
   from disk)

I have succesfully recovered most of the files from the tape saveset
using a
commercial package called 'vbackup' v2.44 by BBC, so I believe the data
on the
tape is fine.  However, no matter what method I use to transfer the
saveset to
disk, 'vbackup' falls over a small way into processing the saveset (but
it
works fine from tape).

Notes:

    I am not a unix guru, so general instructions probably won't help me
    much - they'll need to be fairly cookbook specific.

    I have tried some combinations using 'dd' - fail

    Some of the files I restored were actually savesets in themselves,
    and I was able to use 'vbackup' with them, so I'm confident of my
    use of 'vbackup'.

    I've tried a version of 'ansitape' - close, I got the file to disk,
    but 'vbackup' crashed with a CRC error.

    I am using SunOs 5.5.

    If you know of a version of 'ansitape' that DEFINITELY works for
    what I want, can you point me to the (ftp?) site?  There seem to be
    lots of variants around, with different command-line options, and
little
    matching documentation that I could find.

Why do I want the saveset if I already have recovered the component
files?
Because 'vbackup' doesn't quite do everything right - it's very good,
but not
quite 100.00%.  Also, messy to restore Owner, privs etc.

Thanks
