This article will describe how to backup and restore Ambari service-related settings & databases which might be necessary for the service restore.


Current Ambari does not have any HA (High Availability) features, so it is important to backup the Ambari configuration in the following cases:

  1. Moving Ambari-Server to a different node.
  2. Ambari Server Upgrade.
  3. Operating System patching/upgrade.

IMPORTANT NOTE: This procedure will only backup the Ambari server configuration settings. Ambari also has a backend database that should be backed up using the database vendors recommended settings.
