Here is the condition: Suppose I have a volume pool named 'BMR' and all cartridges/media IDs in it are full with multiple retention levels. Some backup IDs that were using 'BMR' volume pool were expired a days ago, but all media IDs in 'BMR' volume pool are still having the same media status (full with multiple retention levels). I can force the media ID (not the backup ID) to be expired and free it up by using this command: /usr/openv/netbackup/bin/admincmd/bpexpdate -m media_id -d 0 But, by using the above command, it will delete all of the backup IDs in that media ID, which I don't want it. What I want is to delete only certain backup IDs in a media ID and free up some space in that media ID. I've tried to use this command: /usr/openv/netbackup/bin/admincmd/bpexpdate -backupid backup_id -d 0 But it doesn't free up some space in the media ID, it just expires the backup ID. I've waited for the 'Image Cleanup' to run and hope it will free up some space at the above media ID. The Image Cleanup was finished successfully, but it didn't free up some space at the above media ID. >From the Image Cleanup log, I guess it just free up some space at the staging disk only, doesn't it? If it does, then how can I force the expired backup ID to be able to free up some space in its media ID as soon as it was expired? Thank you for helping. -- Best Regards, Adrian _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
