Deleting backup images
Imagedeletionmaybe timeconsuming.Therefore,ifyou deleteimagesmanually,
Symantec recommends the following approach.
See “Data removal process” on page 118.
To delete backup images manually
1
Expire all of the images by using the bpexpdate command and the
-notimmediateoption. The-notimmediateoption preventsbpexpdatefrom
calling the nbdelete command, which deletes the image.
Without this option, bpexpdate calls nbdelete to delete images. Each call to
nbdelete creates a job in the Activity Monitor, allocates resources, and
launches processes on the media server.

command with the –allvolumes option.
Onlyone job iscreated inthe Activity Monitor,fewer resources areallocated,
and fewer processes are started on the media servers. The entire process of
expiring images and deleting images takes less time.
