Preparations for disaster recovery

Before you need to perform disaster recovery, there are several tasks that must be accomplished to ensure the ability to recover.

Procedure

  1. Take a backup of the IBM Data Cataloging system as described in Backup and restore.
  2. Record the installation configuration, including:
    • Network settings
    • Storage settings
    • CPU and memory
    • IBM Data Cataloging version
  3. Ensure that the physical and virtual infrastructure is available to replace the system that might fail.
  4. You cannot recover to a different version of IBM Data Cataloging. If a change of version is required, you need to recover to the current version before you install the upgrade.
    If you perform a recovery on a system that is upgraded, it is recovered directly to the upgraded IBM Data Cataloging version. For example, if IBM Data Cataloging 2.0.0.3 is deployed and then upgraded to IBM Data Cataloging 2.0.1 and then recovered from a failure, the recovery goes directly to the 2.0.1.
