Copying Current State from a Redundant Storage Manager (SM)

To copy current state from a redundant SM, you must shut down the redundant SM and make a copy of its archive and journal directories. This method allows you to create the database copy with no interruption in service to your database. Shutting down an SM decreases the number of failures that the database can tolerate. Therefore, the recommendation is to provision enough resources so that you can shut down an SM without dropping below the database’s fault tolerance.

To have a redundant SM that can be shut down without dropping below the database’s fault tolerance, you should be running a multi-host database on at least three machines. This ensures that at least two SMs continue to run while a third SM is temporarily shut down.
