The other factor to consider is that you should have the delay period for volume reuse on your tape storage pools set equal to the length of time you keep your database backups. Depending on how often you perform reclamation of those pools, these could add up too!

If you think you would never use that 30 day old TSM DB backup, you don't need to keep it. I think a DB retention of 5-10 days is more common. And no, you can't put the TSM DB backups in a storage pool. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Vats.Ashok Sent: Wednesday, April 05, 2006 1:39 PM To: [email protected] Subject: Re: TSM DB backup question Hi List, We have tsm 5.3.00 on AIX. We run TSM database backup which runs once / every day consumes media from scratch pool. We keep these backups for at least 30 days. consuming almost 30 *200 GB tape media. Our data base is about 161 GB so my question is can we reduce the retention time of TSM db backup to 7 days. I am not sure what are the factors which decides how long we need to keep these volumes around. Also Does anybody have a storage pool defined for TSM DB backups. is it possible to do that ?
