Please help me.
I am backing up 7 nodes, running TSM 5.1 on AIX 5.1 and AIX 4.3.3. Total data backed up = +- 300 GB. I am using an LTO3583 library, with 3 x 3580 drives, across a SAN.
Backup times are great, but TSM is being v. wasteful with tapes using up to 7 tapes every night, some of them only have 0.7% utilization.
I am not using collocation, or a copy pool. I tried to use a diskpool on my shark and then move the data to tape, but , SANergy is not supported by IBM.
Does anyone have any suggestions.???
do you do reclamation? inventory expiration? 300GB/day seems like an awfull lot for just 7 nodes... do you do proper incrementals?
btw, copypools are a good idea, tapes do fail when you try to read them (according to murphy...)
