Backup and restore with high-availability clusters

You cannot perform most backup and restore operations on secondary servers.

Before you can establish a server as an HDR (high-availability data replication) or RS (remote stand-alone) secondary server, you must perform a cold restore on it.

After you have set up a server as an HDR or RSS secondary server, you can only perform the following backup and restore operations:
  • You can perform a logical restore on HDR or RS secondary servers when you are setting up a high-availability cluster.
  • You can perform an external backup on an RS secondary server. For more information, see the IBM® Informix® Backup and Restore Guide.

SD secondary servers must be shut down during a cold restore of the primary server, but can be online during a warm restore, after they have been shut down and restarted.
