Note that the use of the /IMAGE qualifier as specified in the base note
does not allow input file selection. The entire disk will be copied.
A better solution would be to mark the unwanted files /NOBACKUP. While
this would "save" the file onto tape, the saved portion would only
consist of the name and allocation of the file not its contents. This
is how system pagefiles are "saved". It makes no sense to save the
contents of a pagefile, but the size and name are required.
Mark the files SET FILE/NOBACKUP, perform the BACKUP, then mark the
files with /BACKUP as appropriate.
This avoids copying files to the backup tapes unnecessarily.
