Perform a replication action and recover data to a
DD system other than the
Cyber Recovery vaultDD system.
Prerequisites
The production and
Cyber Recovery vaultDD systems must include an additional replication context. From the
Cyber Recovery vault, enable the replication context and initialize it.
About this task
An alternate recovery recovers a point in time (PIT) copy quickly from the
Cyber Recovery vault to the
DD production system or an alternate
DD system. The alternate
DD system can be at any location.
NOTE To recover data to an alternate
DD system in a
Google Cloud Platform deployment, an egress firewall rule in the replication VPC (Private Network 2) is required to allow replication traffic to the alternate
DD system.
Steps
Create a VPC peering between the VPC of the alternate
DD system and the replication VPC (Private Network 2) of the
Cyber Recovery vaultDD system.
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.
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.
On the
Cyber Recovery vaultDD system, create a recovery
MTree and then enable and initialize the replication context. For example:
The replication source must be on the
Cyber Recovery vaultDD system and replication destination must be on the production
DD system or an alternate
DD system.
On the production
DD system, run the following command, using the same syntax as in the previous step:
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>
On the
Cyber Recovery vaultDD system, run the following command:
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.
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.
