Disks are actually very reliable these days. I would suggest keeping
the database on local disk, and using your NFS server to keep backup
copies - either by exporting to LDIF or by copying the DB files directly
(though you need to read the Sleepycat docs carefully if you choose to
copy DB files).

SQL storage is possible, but the SQL backend is really there to allow
LDAP access to *existing* SQL data. The LDAP data model is rather different
from the relational model, so there are some limitations when doing
this.
