Poor restore onbar TSM

Hello everyone. I have a slow restore with onbar and TSM. My environment is: Informix Version is 11.50 FC3 in Solaris 10. TSM Server 5.5.3 in Windows 2003 R2 64bits TSM Api 5.5.2 I took a backup and this activity was very speed but the restore was very slow. Backup time: 3 minutes. Restore time: 20 minutes. Anybody have idea how to improve speed. Thank a lot Servio Velasco

have you tested your network throughput speed from the tsm server back to the database server? Maybe there is a network switch setting issue or card setting issue that is causing slow transfer going back. ________________________________ From: ids-bounces@iiug.org [ids-bounces@iiug.org] On Behalf Of SERVIO VELASCO [servio_velasco@hotmail.com] Sent: Thursday, July 09, 2009 5:35 PM To: ids@iiug.org Subject: Poor restore onbar TSM [16306] Hello everyone.

Our network is 1000 Mbps.The throghput speed in the moment to backup was 750 - 950 Mbps. But when restored network used was 10 or 15 % I used ontape and put the backup file in the same disk where is the primary pool (TSM). The difference time of the process to backup and the restore was 1 second. size of ontape file: 5.0 Giga time ontape -s -L 0: 4 mins, 22 seconds time ontape -r: 4 mins: 23 seconds Other idea please.
