Again, this is NDMP.  NBU isn't looking at anything.  It's telling the
NDMP host "please take a diff backup of everything in this path since
this point in time".

What the NDMP host does with that information (how it interprets what
has changed) is beyond the direct control of NBU or any backup
software.  

However, it is possible that the behavior is controllable within the
NDMP host.  But that's up to Isilon, not NBU.  Either check the
documentation or open a ticket with them and see if this is possible.
NBU can pass in environment variables to NDMP.  As an example, you can
tell the NDMP server to use TAR or DUMP as the file format.
