The steps to create a client "ABO" to back up critical volumes for disaster recovery and to use the feature that allows for a single high-density file system to be split into multiple concurrent save sets are as follows:

• Create the client:

• On the NetWorker server, open the NetWorker Management Console.
• Go to the Clients tab.
• Click on the Add button.
• In the Client Name field, enter "ABO".
• In the Client Address field, enter the IP address or hostname of the client.
• In the Platform field, select the appropriate platform for the client.
• Click on the OK button to create the client.

• Configure the client:

• Go to the Clients tab.
• Click on the ABO client.
• Go to the File Systems tab.
• Click on the Add button.
• In the File System field, enter the path of the critical volume that needs to be backed up.
• In the Save Set field, enter a name for the save set.
• Check the Include all blocks that are in use option. This will ensure that all blocks that are in use in the file system are backed up.
• Click on the OK button to add the file system.

• Configure the save set:

• Go to the Clients tab.
• Click on the ABO client.
• Go to the Save Sets tab.
• Click on the save set that you just created.
• Go to the Advanced tab.
• In the Save Set Options field, enter "PSS:streams_per_ss=6". This tells NetWorker to split the save set into 6 concurrent save sets and send them simultaneously in a backup.
• Click on the OK button to save the changes.

• Schedule the backup:

• Go to the Clients tab.
• Click on the ABO client.
• Go to the Schedules tab.
• Click on the Add button.
• Select the appropriate schedule for the backup.
• In the Save Set field, select the save set that you just created.
• Click on the OK button to schedule the backup.
