# Add Additional Protocol for Backups

If your subclient is configured with only CIFS protocol for backups, and you want to back up NFS exports, or vice-versa, then you can add the additional protocol for the subclient.

## Start the Configuration Wizard

1. From the Command Center navigation pane, go to Protect > Files.

   The Overview page appears.

2. Go to the Files tab, and then click the file server.

   The file server page appears.

3. On the upper-right area of the page, click Add protocol.

   The Plan page appears.

## Plan

1. From the Plan list, select the backup plan to use for the file server.

   Steps to create a new backup plan

   1. Click the add button .

   2. In the Plan name field, enter a name for the backup plan.

   3. From the Storage list, select the storage location for the backups.

   4. Configure the backup plan retention and schedule by choosing one of the following options:

      Use pre-defined settings

      - Under Retention, select Standard retention to retain backups for 1 month.

      Create custom settings

      - Enable the Custom plan toggle.

      - For Retention, specify how long to keep backups (example: 30 days, 1 year).

      - For Backups run every, specify how frequently to run backups (example: daily, weekly).

   5. Click Done.

      The backup plan is created and appears in the backup plan list.

2. Click Next.

   The Backup Content page appears.

## Backup Content

1. To enable CIFS protocol, move the CIFS toggle key to the right, and then follow these steps:

   1. From the Access Nodes list, select the access nodes to use for the file server. You can back up CIFS shares using Windows as well as Linux access nodes.

      An access node is a machine with Commvault software installed to manage communication to and from the protected system. To access your file server via CIFS, the access node(s) requires the Windows File System software or the Linux File System software.

      If you do not have an existing access node that can be used to protect your file server, create a new one.

      Steps to create an access node
      1. Click the add button .

      The Add a new Access node dialog box appears.

      1. Download the backup gateway package and install it on your access node.

      2. Install the access node and authenticate using the authcode provided in the instructions.

      Note

      - By default, only those access nodes with both File System and MediaAgent packages installed are displayed.

      - If a client group is selected as an access node, ensure that each client in the group has connectivity to the array.

      - For streaming, CIFS backup using Linux access nodes is supported only with NetApp, Dell EMC Isilon/PowerScale, NutanixFiles, Qumulo, and Generic vendor types. For other vendors, ensure that a Windows access node is selected.

   2. From the Credentials list, select existing credentials or create new credentials that will be used to access the CIFS shares.

      You must configure CIFS credentials to change the backup content.

      Steps to add new credentials

      To add credentials to the Credential Manager, click the plus button (+), and then specify the following in the Add Credential dialog box.

      1. In the Credential name box, enter the name of the credential.

      2. In the User account box, enter the name of the user account.

      3. In the Password box, enter the password.

      4. In the Description box, you can enter a description of the credentials.

      5. Click Save.

   3. By default, all CIFS shares will be selected for backup. To modify the backup content, move the All CIFS shares toggle key to the left and follow these steps:

      1. In the Content area, click Add, and then choose one of the following methods:

   4. Browse: Select items from the file system.

   5. Custom path: Enter one or more paths manually.

2. In the Exclusions area, click Add, and then use Browse or Custom path to specify items to exclude.

3. To create exceptions, enable Define exceptions, click Add, and then use Browse or Custom path to specify items to exempt from the exclusions.

   Browse

   1. Click Browse.

   2. Enter the Interface path.

   3. Select an access node, and then click Browse.

   4. Select the required items, and then click Save.

   Custom path

   1. Enter a path or filter pattern in the Enter custom path field.

   2. Click the add button.

4. From the Include global exclusions list, select one of the following:

   - Off: Applies only subclient exclusions. This option overrides the Use Global Filters on All Subclients setting.

   - On: Applies both global filters and subclient exclusions. This option overrides the Use Global Filters on All Subclients setting.

   - Use cell level policy: Applies global filters only if Use Global Filters on All Subclients is enabled in Global Filters.

   - Click Add.

5. To enable NFS protocol, move the NFS toggle key to the right, and then follow these steps:

   1. From the Access nodes list, select one or more access node groups or access nodes that will be used to protect the file server.

      An access node is a machine with Commvault software installed to manage communication to and from the protected system. To access your file server via NFS, the access node(s) requires the Linux File System software.

   2. By default, all NFS exports will be selected for backup. To modify the backup content, move the All NFS exports toggle key to the left and follow these steps:

   3. In the Content area, click Add, and then choose one of the following methods:

   4. Browse: Select items from the file system.

   5. Custom path: Enter one or more paths manually.

6. In the Exclusions area, click Add, and then use Browse or Custom path to specify items to exclude.

7. To create exceptions, enable Define exceptions, click Add, and then use Browse or Custom path to specify items to exempt from the exclusions.

   Browse

   1. Click Browse.

   2. Enter the Interface path.

   3. Select an access node, and then click Browse.

   1. Enter a path or filter pattern in the Enter custom path field.

   2. Click the add button.

8. From the Include global exclusions list, select one of the following:

   - Off: Applies only subclient exclusions. This option overrides the Use Global Filters on All Subclients setting.

   - On: Applies both global filters and subclient exclusions. This option overrides the Use Global Filters on All Subclients setting.

   - Use cell level policy: Applies global filters only if Use Global Filters on All Subclients is enabled in Global Filters.

   - Click Add.
