PowerProtect Data Manager 19.11 Cyber Recovery User Guide

Retrieving your preserved Cyber Recovery configuration

Use a disaster recovery (DR) backup to return your Cyber Recovery configuration to the state before a management server failure. Retrieve the backup data and then perform a recovery.

1. On the DD system, create an NFS export to map to the Cyber Recovery management host on which you want to perform the recovery. Ensure that you use the no_root_squash option for the NFS export:

   nfs add /data/col1/drbackups <hostname>(no_root_squash)

2. On the Cyber Recovery management host, mount the NFS export to a specific directory:

   mount <DD hostname>:/data/col1/drbackups /mnt/drbackups

   The DR backup files are accessible for the recovery procedure.
3. Access the backup data and perform the recovery.
4. After you recover the Cyber Recovery configuration, perform the following cleanup steps:
   1. On the Cyber Recovery management host, run the following command:

      umount /mnt/drbackups

   2. On the DD system, remove the NFS export that you created in step 1:

      nfs del /data/col1/drbackups <hostname>
      

      The DR backup files are no longer accessible to the Cyber Recovery management host.
