Backup of Small Database - IBM DB2

Trying to devise a cheap and efficient way to backup a relatively small db2 database. Windows, around 1-2 gigabytes total all-inclusive, db2 8.1.2. I have no money to do Tivoli or anything even vaguely like that. BACKUP command is useless because it doesn't compress, and if a tablespace is MANAGED BY DATABASE, it backs up the total space, most of which is blank. Have people dealt with the zip utilities? Anything else known from Veritas or any other 3rd party? Stan...

    Default Backup of Small Database

    Trying to devise a cheap and efficient way to backup a relatively
    small db2 database. Windows, around 1-2 gigabytes total
    all-inclusive, db2 8.1.2.

    I have no money to do Tivoli or anything even vaguely like that.
    BACKUP command is useless because it doesn't compress, and if a
    tablespace is MANAGED BY DATABASE, it backs up the total space, most
    of which is blank.

    Have people dealt with the zip utilities? Anything else known from
    Veritas or any other 3rd party?

    You can use Veritas NetBackup or Legato, but I don't think you'll save
    much money compared to TSM.

    If space is an issue, why not just zip the backup after it's complete?
    This works fine, I've done this many times. On unix platforms you
    can backup to a named pipe and compress the output without an
    intermediate step, but I'm not sure how to do this on a windows
    platform.

    Also, have you considered delta or incremental backups? After the full
    backup these will only contain the pages that changed since your last
    full/incremental/delta backup.


    Good luck,

    To add to this, the "jungle drums" would tell us that backup file
    compression will be with us very soon (in one of the next few fixpacks).

    Actually, it backs up only to the high-water mark and skips any free space.
    If you're seeing far more pages backed up than should be required for the
    amount of data you have, try REGORing your data to make it fit into the
    tablespace better.
