Step 1

Review optimized duplication

See About MSDP optimized duplication within the same domain.

Step 2

Configure the storage servers

See Configuring a storage server for a Media Server Deduplication Pool.

One server must be common between the source storage and the destination storage. Which you choose depends on whether you want a push or a pull configuration.

See About the media servers for MSDP optimized duplication within the same domain.

For a push configuration, configure the common server as a load balancing server for the storage server for your normal backups. For a pull configuration, configure the common server as a load balancing server for the storage server for the copies at your remote site. Alternatively, you can add a server later to either environment. (A server becomes a load balancing server when you select it in the storage unit for the deduplication pool.)

Step 3

Configure the deduplication pools

If you did not configure the deduplication pools when you configured the storage servers, use the Disk Pool Configuration Wizard to configure them.

See Configuring a disk pool for deduplication.

Step 4

Configure the storage unit for backups

If you use a pull configuration, do not select the common media server in the backup storage unit. If you do, NetBackup uses it to deduplicate backup data. (That is, unless you want to use it for a load balancing server for the source deduplication node.)

Step 5

Configure the storage unit for duplication

Veritas recommends that you configure a storage unit specifically to be the target for the optimized duplication. Configure the storage unit in the deduplication node that performs your normal backups. Do not configure it in the node that contains the copies.

Also select Only use the following media servers. Then, select the media server or media servers that are common to both the source storage server and the destination storage server. If you select more than one, NetBackup assigns the duplication job to the least busy media server.

If you select only a media server (or servers) that is not common, the optimized duplication job fails.

Step 6

Configure optimized duplication bandwidth

Optionally, you can configure the bandwidth for replication.

See About configuring MSDP optimized duplication and replication bandwidth.

Step 7

Configure optimized duplication behaviors

Optionally, you can configure the optimized duplication behavior.

See Configuring NetBackup optimized duplication or replication behavior.

See About configuring MSDP optimized duplication and replication bandwidth.

Step 8

Configure a storage lifecycle policy for the duplication

Configure a storage lifecycle policy only if you want to use one to duplicate images. The storage lifecycle policy manages both the backup jobs and the duplication jobs. Configure the lifecycle policy in the deduplication environment that performs your normal backups. Do not configure it in the environment that contains the copies.

See About storage lifecycle policies.

See Creating a storage lifecycle policy.

Step 9

Configure a backup policy

See About MSDP backup policy configuration.

See Creating a backup policy.

Step 10

Configure NetBackup Vault for the duplication

Configure Vault duplication only if you use NetBackup Vault to duplicate the images.

Configure Vault in the deduplication environment that performs your normal backups. Do not configure it in the environment that contains the copies.

Step 11

Duplicate by using the bpduplicate command

Use the NetBackup bpduplicate command only if you want to duplicate images manually.

Duplicate from a Media Server Deduplication Pool or a PureDisk Deduplication Pool to another Media Server Deduplication Pool in the same domain.
