Wish I could be some help, but the last time I worked with NetApp I passed on SnapManager for SQL as backups and restores were done at the volume level (I believe), meaning if you were not constantly managing where dbs where you could have to restore multiple dbs just needing to do a restore of one.
Just curious have you checked the NetApp support sites? Have you seen this forum post?
