unable to increase retention period of backup image
master , media, client OS linux NBU ver 188.8.131.52 , backup goes to data domain box model number DD670 -- copy 1, then duplication to tape. copy 2 n copy 3. customer requested to increase retention period of backup image which is on DD box.
first used bpimagelist to determine images for particular client.
then used bpexpdate -recalculate -backupid <servername_134665620821> -copy 1 -d 09/02/2013 13:00:00 -force .it executed successfully. but problem is when i tried to cross verify after 4 hrs that retention period increased on backup image or not it still shows the same retention period.
could not understand why it is so even though bpexpdate was successfully executed.
