Hi All,

We currently have a large 2.6TB (ever growing) SAP database that we
perform a full hot archive on each day. The primary DB server sync's a
BCV mount, and then we backup the mirror directly on the TSM server.
The TSM server is an IBM H80 running AIX 5.1.0.5, TSM Server 5.2.2.0,
and connects to a 3494 library that contains 10 3590EA1 drives. This
backup generally takes about 12-13 hours to complete. The backup is
setup to use 4 drives for the primary copy, and additional 4 to copy to
the offsite pool simultaneously.

 I know an incremental backup would help somewhat with media
consumption, but not all that much since we expire the data every 14
days and get a return on the media. I have been asked by management if
moving to an incremental backup would help performance? Does anybody
have any experience backing up an SAP Oracle DB of this size
incrementally? What is the best performing cost effective way to backup
2.6TB?

Any insight would be much appreciated!


Thanks,

Greg
