Hello. I have a LTO Ultrium Ultrascalable Tape Library 3584 L32 and this library has three (3) drives LTO Ultrium I (First Generation). Every day the TDP for R/3 (version 3.2.0.8) takes backups online of database's SAP (Oracle) through TSM Server 4.2. This TSM Server is running on an RS/600 with AIX 4.3.3. With these tree drives LTO, the backup lasts between 7 and 8 hours and the average transmission rate was about between 200 GB/h (62 MB/sec) and 260 GB/h (74 MB/sec). This database's size is 1.660 GB. Well, As I need to reduce the backup's time till 4 hours or down, how can I find out this solution? Must I allocate others extra drives in order to reduce the backup's time? I am not sure if it will be reduce the backup's time with the others drives Ultrium because I have proved the backup with four drives and his time was not reduced and his result was the same 260 GB/h (74 MB/sec). I need your comments and I very much look forward to hearning you. Thank you very much.
