Data backup requirements

There are items to consider for data backup before you configure hosts for High-availability (HA).

If a backup archive originates on an HA cluster, click Deploy Full Configuration to restore the HA cluster configuration after the restore is complete. If disk replication is enabled, the secondary HA host immediately synchronizes data after the system is restored.

If the secondary HA host is removed from the deployment after a backup is completed, the secondary HA host displays a Failed status on the System and License Management window.

For more information about restoring backup archives in an HA environment, see the IBM® QRadar® Administration Guide
