Hi Steve, i think ist better to use the client cpu for that task to save disk space and cpu at the tsm server. That also reduces networkload for backup and restore. We use compression at the client on all tsm clients including TDP for SQL for a long time. The load during backuptime is typical low, so we can use the cpu for that task without problems. We are quite satisfied with the performance of that solution.

Comments on performance, etc? We are investigating use of a multi TB raid5 array to use as a buffer between our local primary disk pool and the tapepool. Have seen the posts regarding file vs disk device classes but what about compression? Good, bad, etc. Win 2000 sp4 with TSM server 5.2.3.2 -- Steve Bennett, (907) 465-5783 State of Alaska, Enterprise Technology Services, Technical Services Section
