Ruksana,

there is no simple answer, it depends.
If you make two backups to a primary pool and just send one set of tapes
off-site it would expire.If you backup primary pool to copypool it is
same.
One method to retain "forever" first backup and expire next one (with
consequent ones) is to use two node names (with different policies) for
same box. The other method is to use archive instead of backup. Thus on
27-th you create archive with RETVer=NOLimit or very long retension and on
29-th you have regular incremental backup with retextra=92.

Subject:        Re: Backup retention period

Hi Zaltko,

Sorry to bother you again. I understood the concept of VEREXIST AND
RETEXTRA.

We have done a offlinebackup on 27th may and a online backup on 29th.For
me
the offline backup is the most imp one if I had to restore.

if I do the verexist=unlimit and retextra=92 will the inactive backups ie
the offline and the online which I have done ( I have done no backup since
thelast offline and online ) will stay there for the period mentioned.

is there anyway to let TSM know to hold the offline backup forever till I
ask it to delete so ..?

I appreciate any help from you.

With regards,
