Plan for backup and recovery

Developing backup and recovery procedures at your site is vital to avoid costly and time-consuming losses of data. IBM MQ provides means for recovering both queues and messages to their current state after a system failure.

Recovery procedures

Develop the following procedures for IBM MQ:

• Create a point of recovery.
• Backing up page sets.
• Backing up CF structures.
• Recovering page sets.
• Recovering from out-of-space conditions ( IBM MQ logs and page sets).
• Recovering CF structures.

See Administer IBM MQ for z/OS for information about these. Become familiar with the procedures used at your site for the following:

• Recovering from a hardware or power failure.
• Recovering from a z/OS component failure.
• Recovering from a site interruption, using off-site recovery.

• Tips for backup and recovery
  Use this topic to understand some backup and recovery tasks.
• Recovering page sets
  Use this topic to understand the factors involved when recovering pages sets, and how to minimize restart times.
• Recovering CF structures
  Use this topic to understand the recovery process for CF structures.
• Achieving specific recovery targets
  Use this topic for guidance on how we can achieve specific recovery target times by adjusting backup frequency.
• Backup considerations for other products
  If we are using IBM MQ with CICS or IMS then we must also consider the implications for the backup strategy with those products. The data facility hierarchical storage manager (DFHSM) manages data storage, and can interact with the storage used by IBM MQ.
• Preparing for recovery on an alternative site
  If a total loss of an IBM MQ computing center, we can recover on another IBM MQ system at a recovery site.
• Example of queue manager backup activity
  This topic shows as an example of queue manager backup activity.
