Essentially that's what you were asking us for in your first 
message. A backup that only copies new or changed files from source 
to destination is an incremental backup.

Contrasted to an "archival backup" or "full" backup which copies 
everything from the source to the destination regardless.

Which one is best for you depends upon your chosen backup scheme.

Note that an incremental backup to an empty destination has the same 
effect as doing a full backup.

/BU is a good general purpose incremental backup option because it 
includes copying "hidden", "system", and "read only" files. It also 
copies files in the subdirectories.
