Can you post the end of job statistics? For example, in my dsmsched.log, I have: 05/18/06 22:32:33 --- SCHEDULEREC STATUS BEGIN 05/18/06 22:32:33 Total number of objects inspected: 845,061 05/18/06 22:32:33 Total number of objects backed up: 26,665 05/18/06 22:32:33 Total number of objects updated: 0 05/18/06 22:32:33 Total number of objects rebound: 0 05/18/06 22:32:33 Total number of objects deleted: 0 05/18/06 22:32:33 Total number of objects expired: 1,260 05/18/06 22:32:33 Total number of objects failed: 0 05/18/06 22:32:33 Total number of bytes transferred: 3.11 GB 05/18/06 22:32:33 Data transfer time: 464.32 sec 05/18/06 22:32:33 Network data transfer rate: 7,040.43 KB/sec 05/18/06 22:32:33 Aggregate data transfer rate: 2,600.08 KB/sec 05/18/06 22:32:33 Objects compressed by: 0% 05/18/06 22:32:33 Elapsed processing time: 00:20:57 05/18/06 22:32:33 --- SCHEDULEREC STATUS END If you can post yours for that backup run, it would help give some insight. Also, do you use a disk pool on the TSM server? For example: TSM client -> TSM server (diskpool) -> TSM server (tapes) If you do not use a diskpool, you will not be able to feed data to the LTO-3 tape drives fast enough. If that happens, it will do start-and-stop which dramatically slows down performance. -Dan
