Dell PowerProtect Cyber Recovery 19.12 on Google Cloud Platform Deployment Guide

Recovering data to an alternate DD system

Perform a replication action and recover data to a DD system other than the Cyber Recovery vault DD system.

1. Create a VPC peering between the VPC of the alternate DD system and the replication VPC (Private Network 2) of the Cyber Recovery vault DD system.
2. From the Google Cloud Platform console, manually create an egress firewall rule in the replication VPC (Private Network 2) using the following parameters:
   • Direction of traffic: Egress.
   • Targets: Specified target tags.
   • Target tags: The network tag of the Cyber Recovery vault DDVE. The details for the Cyber Recovery vault DDVE VM provide this tag.
   • Destination filter: IPv4 ranges.
   • Destination IPv4 ranges: The IP address used for replication on the alternate DD system (for example, 10.0.0.14/32).
   • Protocols and ports: Specified protocols and ports.
   • Protocol: TCP.
   • Port range: 2051.
3. Perform the following one-time steps to set up to recover data to an alternate DD system.
   You need only perform these steps again if you change the name of the recovery MTree.
   1. On the Cyber Recovery vault DD system, create a recovery MTree and then enable and initialize the replication context. For example:

      mtree create /data/col1/<mtree name>
      
      replication add source mtree://<Vault DD Name>/data/col1/<MTREE Name> destination mtree://<Prod DD>/data/col1/<MTREE Name>-repl
      
      replication modify mtree://<Prod DD>/data/col1/<MTREE Name>-repl connection-host <Production DD Replication IP Address>
      

      The replication source must be on the Cyber Recovery vault DD system and replication destination must be on the production DD system or an alternate DD system.

   2. On the production DD system, run the following command, using the same syntax as in the previous step:

      replication add source mtree://<Vault DD Name>/data/col1/<MTREE Name> destination mtree://<Prod DD>/data/col1/<MTREE Name>-repl

   3. On the production DD system, run the following command, ensuring that you use the Cyber Recovery vault replication IP address in place of <Production DD Replication IP Address>:

       replication modify mtree://<Prod DD>/data/col1/<MTREE Name>-repl connection-host <Vault Replication IP Address> 
      	    

   4. On the Cyber Recovery vault DD system, run the following command:

      replication initialize mtree://<Prod DD>/data/col1/<MTREE Name>-replreplication initialize mtree://<Prod DD>/data/col1/<MTREE Name>-repl

4. Run the CRCLI recovery command.
   The following is an example of the command to recover data to an alternate DD system:

   crcli recovery run --action recover-to-alternate --policyname policy1 --copyname cr-copy-policy1-20180202000102 --recoveryMtree /data/col1/cr-recover-to-alternate --ethernetPort ethV1 --watch 15

5. When the command in the preceding step is completed, on the production DD system, fast copy the data to the appropriate MTree or storage unit as required by the backup application that you are using. Run the following command:

   filesys fastcopy source <folder of source MTree> destination <folder of destination MTree>

   where:

   • <folder of source MTree> is the folder of the MTree that was replicated.
   • <folder of destination MTree> is the folder of the MTree that the backup application recommends or where you want the data.
6. Depending on which backup application you use, see the Avamar, NetWorker, or PowerProtect Data Manager documentation for information about how to perform a DR recovery.
