If I dedicate 2 drives to the Netapp and have the zoning setup properly
will the media servers use those drives for regular backups as well?

Steve,
OK- I forgot about one of the key elements: the NDMP backups do actually
run through the media servers via Remote NDMP.  They are still using
NDMP, but our solaris/windows media servers handle the tape drives for
them.


Sorry for the misinformation- the devil is in the details.
