    Gotta disagree with AZC

    No, a differential will NOT delete files, but it will restore any files that were backed up, overwriting any that exist (if you tell it to do so)

    Since TEST.TXT was  backed up on Monday's backups it will be restored when you restore the Monday Full,  and will still be there after you restore the Tuesday DIfferential

    The Symantec respose to this situation is the Synthetic backup.   This uses a previous full (or synthetic) and an incremental to produce a backup set that is the same as it would be if a full were done at that time

Thanks for answering my question but now I have another.
Is there any way to preserve these deletes?  The reason I ask is if I have to do a disaster recovery using the Full and differential backups and users deleted files between the full and differential they will wonder why the files are back.  Not to much of a big deal since the way our data grows I doubt if anyone does delete files but it would be nice if there was a way.
