  1. Best backup software for DAT tapes?

    This is probably an FAQ...

    Since 1996 I have been using Seagate Backup Exec, version 6.something.

    It's rubbish really but worked OK for NT4. The worst part of it is
    lousy error recovery and in particular its inability to display the
    total backup size before it starts to write to a tape. So, unless I
    *know* that the tape will be big enough for the data, I have to use
    Windows Explorer, Properties and check the size of the data.
    Otherwise, the thing just gets to the end of the tape and asks for
    another one to be inserted. I never do that; if I need more than one
    tape I backup different machines (this is over an ethernet LAN) to
    different tapes, etc.

    Another stupid feature of BE is that one cannot restore a tape which
    cannot be catalogued, and if a tape has a fault near its end, or if in
    a multi-tape set one of the tapes has a fault, no restore at all can
    be done. I've used a specialised generic tape reading program in such
    cases which just dumps everything on the tape to a specified folder.

    More recently I tried a current version of BE. It didn't seem to
    actually work any better, and on one machine it completely trashed the
    hard disk...

    Also, we now run win2000 and win2000 has certain open files which BE
    won't backup. There are always some .TMP files which prevent a backup
    completing, and they have to be manually skipped.

    Is there something that is a LOT nicer, and makes it easy to determine
    the backup size (in GB) before one commits to writing to the tape, and
    works fully with winNT, win2000, winXP?

    We use HP DDS3 and DDS4 drives, SCSI attached via Adaptec SCSI cards.

    I think it's time to update your software........


    backup Exec has changed ownership, if we're talking about the same
    product. I used Veritas Backup Exec on the 7.something and it worked
    fine. They seem to be up to version 10. I assume something's
    changed.

    These days I'd look for disk-to-disk-to-tape backup strategy. I'd like
    to think that Veritas can do that now.

    I did test the Veritas version; it's really no better. No backup size
    determination before the tape writing starts. And it crashed big-time.

    No takers apparently, but I can report that windoze's own backup
    program does exactly what I need, and works.

    Next, I will try to see if it is tape format compatible with Veritas
    BE10. Might be, given they come from the same code base.

    Can't select software/hardware compression though...
