Backup and recovery

We can back up Coupling Facility list structures using the WebSphere MQ command BACKUP CFSTRUCT. This puts a copy of the persistent messages currently within the CF structure onto the active log data set of the queue manager making the backup, and writes a record of the backup to DB2.

In the event of a Coupling Facility failure, we can use the WebSphere MQ command RECOVER CFSTRUCT. This uses the backup record from DB2 to locate and restore persistent messages from the backup of the CF structure. Any activity since the last backup is replayed using the logs of all the queue managers in the queue-sharing group, and the CF structure is then restored up to the point before the failure.

For more information about the BACKUP CFSTRUCT and RECOVER CFSTRUCT commands, see the WebSphere MQ Script (MQSC) Command Reference.
