Use the Delete volhist command to set your retention.
del volhist tod=today-7 tot=now t=dbb

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 ?

Thanks,
Ashok
