Dear All,

my tsm server is on windows version 6.3.4
tdpo clients are on aix with version 5.3

My daily TDPO full backup is not delete any backup from rman and tsm. its not find any absolete backup from
rman side.
In rman configuration its set for 07 days retention only. but through rman i can see 2-3 months old backup.

my rman script use below commands:

""""""""""""
change archivelog all crosscheck;
DELETE NOPROMPT ARCHIVELOG UNTIL TIME "SYSDATE-2";

resync catalog;
report need backup;
show all;
delete noprompt obsolete;
list backup summary;
EOF
""""""""""
after checking the daily log its says "not found any obsolete backup" which is strange. as per retention
policy should delete backup older then 07 days.


To delete the backup from rman i have to modify the script with below details:


""""""""""""""""""""""""""""""""""
change archivelog all crosscheck;
DELETE NOPROMPT ARCHIVELOG UNTIL TIME "SYSDATE-2";

resync catalog;
report need backup;
show all;
delete noprompt obsolete;
delete noprompt expired backup;
list backup summary;
EOF
"""""""""""""""""""""""""""""""""
the problem here is using this delete script its delete all my daily backup and just keep one day backup
instead of keeping last 07 days backup.

once i run the delete script and delete all the rman backup from all servers, using tdpo sync utility i can
expire data from tsm and can empty my tapes.

this is very lengthy and critical exercise so need your help and comments.
