6. When would I, or would I not, use cross mount points?
Ans: If you have a file list without selecting the cross mount point then, at your example, netbackup will backup only the mount point (32 Kilobytes backup) and not the files inside the mount point.
You have to select the cross mount point at the police’s attributes to backup the files inside the mount point.
Do not to select cross mount points and “ALL_LOCAL_DRIVES” together. This will give you a double backup
