Just make sure you *expire* the disk copy, not *delete* it.  

The end result is the same, the files are removed from the disk, but if you
just delete the disk copy, then Netbackup's image catalog still thinks it's
there.  This will make it try to use it for restores and it'll unnecessarily
increase the size of your catalog.

Take a look at the image file, should show both locations once it is written
to tape and before it is deleted from disk (whatever the reason may be). As
for never deleteing from disk, if your shop is anything like mine we don't
have a year worth of disk to keep all my backups there, have about 3 days
worth (60tb) so it gets deleted from disk ;)

5.0 does a bit more than that.  When a disk staging unit gets full, it
will suspend the backup, write the disk to tape, and resume the backup.
It is also smart enough to realize that when you're doing a restore, if
the data is still on disk (it's not deleted unless it has to be, even if
the data has been copied to tape), then the restore will take place from
disk and not tape.
