Veritas NetBackup™ OpenStorage Solutions Guide for Disk

Configuring optimized duplication to an OpenStorage device within the same NetBackup domain

You can configure optimized duplication from one disk appliance to another disk appliance of the same type.

A NetBackup media server initiates and manages the duplication between appliances. After the duplication completes, the media server connects to the destination appliance to verify the image copy. NetBackup maintains records of the image copies and their locations in the NetBackup catalog.

Table: To configure optimized duplication of deduplicated data

Step

Action

Description

Step 1

Ensure that all requirements are met.

See About OpenStorage optimized duplication within the same domain.

Step 2

Configure optimized duplication behaviors.

Optionally, you can configure the optimized duplication behavior.

See Configuring NetBackup optimized duplication or replication behavior.

Step 3

Select the media server in common.

In the storage unit for the destination disk pool, 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 balances the job load among them.

See Configuring an OpenStorage storage unit.

Step 4

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 OpenStorage environment that performs your normal backups.

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

  • For the Backup destination, select the Storage unit that is the target of your backups.

    The disk appliance for the storage unit contains the primary backup copies; they are the source images for the duplication operation.

  • For the Duplication destination, select the Storage unit for the disk pool on another appliance.

You can apply separate retention periods to each copy. For example, you can retain the source image for three weeks and the destination copy for a longer period of time. If you delete the source image, the copy is not deleted.

See About storage lifecycle policies.

See Creating a storage lifecycle policy.

Step 5

Configure a backup policy

Configure a backup policy only if you use a storage lifecycle policy to manate the duplication.

Configure a policy to back up your clients. Select that storage lifecycle policy in the Policy storage field of the Policy Attributes tab.

See Creating a backup policy.

Step 6

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.

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

  • On the Vault Profile dialog box Choose Backups tab, choose the backup images in the source disk pool.

  • On the Vault 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. Select the profile you created for the OpenStorage duplication job.

See the NetBackup Vault Administrator's Guide.

Step 7

Duplicate by using the bpduplicate command

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

Duplicate from the source storage to the destination storage.

See NetBackup Commands Reference Guide.
