      Steps for disaster recovery readiness

      How to configure Disaster Recovery (DR) setup

      Purpose:

      To ensure correct display of Disaster Recovery (DR) repository details on the Zmanda Management Console (ZMC) UI after a restore operation on the Disaster Recovery server.

      Solution: Implement the following key steps to ensure DR readiness:

      1. License both servers: Once you login to ZMC, obtain the license by providing both primary and secondary server Mac IDs. Upload the license to both servers.

      Note: Only one server will be active at a time.

      2.       Set up a secondary instance (DR server): Deploy a server with identical specifications as your primary server.

      Note: Do not configure anything on the secondary instance. Keep it documented and ready for activation in case of a disaster.

      3.       Configure a DR repository: Choose a physically separate location (ideally off-site) for the DR repository. Configure an SMB share on a third-party server. Provide the server IP, username, and share details for repository access.

      4.     Set up the DR Repository: The drconfig file contains critical DR information. Store it securely in a safe location and treat it with the utmost care.
      Copy the drconfig file from the primary server's /var/lib/amanda/drservice/ directory to the secondary server.

      5.     Configure DR Configuration: 

      • As a root user, run the following commands on the DR server to set up the correct permissions for the drconfig file:

      cp /<path-to>/drconfig /var/lib/amanda/drservice/ && chown amandabackup: /var/lib/amanda/drservice/drconfig && chmod 644 /var/lib/amanda/drservice/drconfig

      Replace the /<path-to>/ with the actual absolute path to the drconfig file.

      Ex: /home/sysadmin/drconfig

      • Run the following command on DR server to import the DR configs:

      /opt/zmanda/amanda/bin/drservice import --source /var/lib/amanda/drservice/drconfig

      6.       Refresh the DR Page: After a restore or configuration, simply refresh the DR page on your backup server. This updates ZMC with the correct repository details.
