Adding a load balancing server | Symantec 7 specs

58Configuring deduplication Adding a load balancing server

■Optimized duplication failover. By default, if an optimized duplication job fails, NetBackup does not run the job again.

■Number of optimized duplication attempts. You can specify the number of times NetBackup retries an optimized deduplication job before it fails the jobs.

■Storage lifecycle policy retries. If the optimized deduplication job is configured in a storage lifecycle policy, NetBackup retries the job three times.

Caution: These settings affect all optimized duplication jobs, not just optimized deduplication copy jobs.

To configure NetBackup to revert to normal duplication if an optimized job fails

◆Add the following entry to the bp.conf file on the NetBackup master server:

RESUME_ORIG_DUP_ON_OPT_DUP_FAIL = TRUE

On Windows systems, NetBackup configuration options are in the Windows registry.

To configure the number of duplication attempts

◆Add an OPT_DUP_BUSY_RETRY_LIMIT entry in the NetBackup behavior file. For example, the following entry configures NetBackup to retry the job four times before NetBackup fails the job:

OPT_DUP_BUSY_RETRY_LIMIT 4

The behavior file resides in the following directories:

■UNIX: /usr/openv/netbackup/db/config/behavior

■Windows: install_path\NetBackup\db\config\behavior.

To configure the number of storage lifecycle policy retries

◆Delay more retries by adding an IMAGE_EXTENDED_RETRY_PERIOD_IN_HOURS entry in the NetBackup behavior file. The default for this value is three hours.

Adding a load balancing server

You can add a load balancing server to an existing media server deduplication node.

See “About deduplication servers” on page 21.
