Backing up a data store

Backing up a data store enables you to restore the data store from the backup if a failure occurs that cannot be dealt with by the system. To back up the tables that comprise a data store, refer to the documentation for the chosen database.

If your relational database management system (RDBMS) is DB2 , and it is being used as the persistent data store, the backup process can use the suspended I/O feature of DB2. With other databases that do not possess this capability, the backup might present a longer interruption to service, or require the messaging engine is stopped while the backup is made. If you attempt to back up the data store for a messaging engine that is still running, you might lose or corrupt important data.

  1. Unless your backup process uses the suspended I/O feature of DB2 stop the messaging engine.
  2. Back up the data store in accordance with the documentation for the chosen database. Include the tables described in Data store tables.
