OmniBack II, DLT4000 - other Backup Issues

Hi,

We are building a data warehouse on a HP9000 (HP-UX 10.2) box using Oracle 7.3 as the backend database server. Our hardware vendor has recommended to buy OmniBack II and DLT4000 5 Catridge Autochanger for our backup and recovery requirements.

The database will be about 100 GB in size with nightly loads from DB2 to Oracle. The database will backed up every day. There will be incremental backups of root and other OS file systems and weekly complete backups. I would like to know your opinion on the following:

+ It is well known that OmniBack is faster compared to SAM Backup &
Recovery (SAM B&R). Which of these two are better to use in my environment? We have no plans now to use OmniBack for anything other than backing up the UNIX system.

+ Do we need DLT4000 5 Catridge autochanger, which is an expensive
product, compared to a simple DLT4000 desktop tape drive that allows only one tape at a time.

+ We were told that backing up using SAM B&R will make backups slower
and the tapes can hold only 16 GB/tape compared to OmniBack II which can hold up to 40 GB/tape.

Any opinions, suggestions or comments are appreciated.

Thank you,
