Veritas NetBackup™ Deduplication Guide

Configuring MSDP optimized duplication within the same NetBackup domain

You can configure optimized duplication from a Media Server Deduplication Pool to other deduplication storage within the same NetBackup domain.

Table: How to configure optimized duplication of deduplicated data

Step

Action

Description

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

In the storage unit for your backups, do the following:

  1. For the Disk type, select PureDisk.

  2. For the Disk pool, select your Media Server Deduplication Pool or PureDisk Deduplication Pool.

Note:

NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.

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.)

See Configuring a Media Server Deduplication Pool storage unit.

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.

In the storage unit that is the destination for your duplicated images, do the following:

  1. For the Disk type, select PureDisk.

  2. For the Disk pool, the destination can be a Media Server Deduplication Pool or a PureDisk Deduplication Pool.

Note:

NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.

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.

See Configuring a Media Server Deduplication Pool storage unit.

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.

When you configure the storage lifecycle policy, do the following:

  • The first operation must be a Backup. For the Storage for the Backup operation, select the storage unit that is the target of your backups. That storage unit may use a Media Server Deduplication Pool or a PureDisk Deduplication Pool.

    These backups are the primary backup copies; they are the source images for the duplication operation.

  • For the second, child Operation, select Duplication. Then, select the storage unit for the destination deduplication pool. That pool may be a Media Server Deduplication Pool or a PureDisk Deduplication Pool.

Note:

NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.

See About storage lifecycle policies.

See Creating a storage lifecycle policy.

Step 9

Configure a backup policy

Configure a policy to back up your clients. Configure the backup policy in the deduplication environment that performs your normal backups. Do not configure it in the environment that contains the copies.

  • If you use a storage lifecycle policy to manage the backup job and the duplication job: Select that storage lifecycle policy in the Policy storage field of the Policy Attributes tab.

  • If you do not use a storage lifecycle policy to manage the backup job and the duplication job: Select the storage unit that contains your normal backups. These backups are the primary backup copies.

    Note:

    NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.

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.

For Vault, you must configure a Vault profile and a Vault policy.

  • Configure a Vault profile.

    • On the Vault Profile dialog box Choose Backups tab, choose the backup images in the source Media Server Deduplication Pool or a PureDisk Deduplication Pool.

    • On the Profile dialog box Duplication tab, select the destination storage unit in the Destination Storage unit field.

  • Configure a Vault policy to schedule the duplication jobs. A Vault policy is a NetBackup policy that is configured to run Vault jobs.

Note:

NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.

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 or another PureDisk Deduplication Pool in the same domain.

Note:

NetBackup supports PureDisk Deduplication Pool storage on NetBackup 5000 series appliances only.
