Ruksana,
the method TSM usilizes is "keep several copies, check to limits, if any
limit is reached delete oldest copy"
So if you have set 31 versions and perform backups weekly last version
would be 31 weeks old. But if you set at the same time versions to stay
for 31 days you will have no more than 5 (sixth would be more than 31 days
and would be "expired").
Most recent copy ("active" one) would stay forever until you delete the
file. At that time next pair of limits (VERDELETED and RETONLY) would take
care of the copies.

Hi Zlatko,
Thanks for your quick response.
According to my TSM the copygroup setting has nolimit for this management
class but the utl file has MAX versions 31.
>From what you said ( my understanding is ) below if I don't do the backup
of this database it should stay forever as it has nolimit -but if I do
perform backup it will stay for next 31 days. Correct me if I'm wrong.
The link you sent me was very useful I will start reading it.
With regards,
Ruksana Siddiqui

The backup would stay there undefinitely if the content does not change.
If it changes and a new backup is performed the copy you've just becomes
obsolete and according to copygroup settings will expire some day. To
ensure it would not be before three months have passed set
VEREXIST=NOLimit and RETExtra=92.
To become familiar with TSM (which is more evolved than competitive
products) I highly recommend you to have a look at nice redbook "Tivoli
Storage Management Concepts" - SG24-4877-02
(http://www.redbooks.ibm.com/). This would save you many headaches.

Subject: Backup retention period
Hi,
I just started working with TSM but can someone tell me how can I find the
retention period of the backup I have done.
I have done a particular backup and wanted to have it for atleast 3 months
-
is there anyway I tell TSM to hold it for 3 months or can I actually check
how long TSM was configured to hold the data.
Any help is highly appreciated.
With regards,
Ruksana Siddiqui
