[jira] [Created] (AMBARI-8068) Ambari Server HA Phase 1: Provide backup and restore capability

Szilard Nemethy created AMBARI-8068:
---------------------------------------

             Summary: Ambari Server HA Phase 1: Provide backup and restore capability
                 Key: AMBARI-8068
                 URL: https://issues.apache.org/jira/browse/AMBARI-8068
             Project: Ambari
          Issue Type: Improvement
          Components: ambari-agent, ambari-server
    Affects Versions: 1.7.0
            Reporter: Szilard Nemethy
            Assignee: Szilard Nemethy
            Priority: Critical
             Fix For: 2.0.0


If the Ambari server host is lost, there should be capability to provision a new Ambari server that can be brought up with most of the existing state. We can assume that the Database would be external and retains its state.
This requires:
Backup feature to periodically backup Ambari non-DB state: keystores, certificates, Ambari server state, agents states
Restore feature to start an Ambari server from a back up. Also, re-point agents to the new Ambari server.
