Snapsure is a checkpointing technology for the Celerra and is a function of
your Celerra's DART code, not the CIFS server.
There are several possible answers to the question of whether "SNAPSURE=Y" is
needed or not, which depend on the version of DART and Networker in your shop.
Check the release notes for your version of NW, as well as the NDMP
documentation for Networker and the NDMP documentation for the Celerra.
The good news is you should be able to have up to 4 streams to separate tape
devices from each datamover. Four is the limit for NDMP.
