To configure an AFTD device on "StorageNodeA" with the name "OracleBackup" using the folder "D:\AFTD" to the pool "Default", the administrator can use the Data Domain CLI (Command Line Interface) to access the Data Domain system and create the AFTD device. Here are the steps:

• Log in to the Data Domain CLI by entering the following command:

ssh admin@StorageNodeA

• Once logged in, create a new AFTD device named "OracleBackup" by entering the following command:

ddboost afd create --name OracleBackup --pool Default --folder D:\AFTD

• Verify that the new AFTD device has been created by running the following command:

ddboost afd show --name OracleBackup

• To make sure that the Oracle backups only use the specific storage node, you can assign the AFTD device to the Oracle backup host by running the following command:

ddboost afd set --name OracleBackup --host OracleBackupHost

• Verify the configuration by running the following command:

ddboost afd show --name OracleBackup

• To make sure that the StorageNodeA is a dedicated storage node, you can configure the storage node to only allow the OracleBackup host to use the AFTD device by running the following command:

ddboost host access add --host OracleBackupHost --afd OracleBackup

Finally, the administrator should select the “Apply” button to save the configuration.

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.
