	DAR has a number of unique capabilities, including restoring deletions, 
which is a very unique feature.  I don't know about you, but my video 
files represent many hundreds of hours of work, and replacing them en 
masse would be a huge and expensive undertaking.  The backup server 
maintains a daily update of all changes and new files.  the server just 
isn't all that expensive, comparatively speaking.  The DAR backup is 
even cheaper, since it is done on old drives removed from the arrays 
during upgrades.  In one sense, they are free.

	DAR allows for not only incremental backups, but also incremental 
deletions.  I find it extremely useful, and allows for as much space 
saving on the live system as one likes.  I suggest you check it out.
