You can use either of two bulk materialization methods to stop updates at the primary database  and take a snapshot.
The two methods are:
Using
the Adaptive Server mount command
 
Using the Adaptive Server dump and load, select,
or bcp command
 
Use these
methods to retrieve data from the primary database if you are able
to suspend updates to the primary data. To maintain consistency,
all updates to the primary database are suspended for the duration
of the materialization.
