I have NetBackup client with 1500 images and I would like to delete (expire) all 1500 images and finally remove the client from NetBackup. I know, that one can use the function <Catalog> within the NetBackup Administration console in order to expire images. However, doing it this way seems to be rather slow.
This command will set a new expirationdate to all backup images of client <clientname>. In this special case it sets the expiration to 0, which was in the past and therfore immediatly deletes the image.
Befor doing such a mass delete, I would do a fresh backup of the catalog.
