I do 1TB+ backups nightly which run for about 8 hours. A large part of our backup is a 500GB Oracle database backup to TSM. The database backups up over a private 1Gb connection to a AIX P660-6h1 server with 2GB of RAM and 4 processors. The data then goes to nine 2disk stripe sets, over a 1Gb SAN connection (I went with stripe sets because RAID5 was just to slow). I'm getting high iowat times on my AIX TSM server. I'm having a hard time pinpointing exactly where the bottleneck is at. Currently it takes 51/2 hours to backup 500GB but I know it can be better.
My question is are any of you that are moving this amount of data faster than me using a more powerful server like a IBM 690.
