# Adding Additional Backup Locations to Disk Storage

You can add additional backup locations to a disk storage. To determine whether more storage is needed, you can view the total storage capacity and the total free space in the general information provided in the specific backup location page. These values are the sum of the capacity and the sum of the free space on all backup locations for the disk storage.

Note

In Feature Release 28 and earlier versions, you were allowed to configure more than one backup location on a disk storage that is already used by another backup location. However, this caused problems with storage space reporting, alerting and billing. From Feature Release 30, you cannot add a backup location on a path that is already used by another backup location in the disk storage.

# Procedure

1. From the Command Center navigation pane, go to Manage > Storage > Disk.

   The Disk page appears.

2. Click the disk storage that you want to add an additional backup location.

   The disk storage page appears.

3. In the Backup locations section, click Add.

   The Add Backup location dialog box appears.

4. Add a MediaAgent, using one of the following options:

   - To use an existing MediaAgent, from the MediaAgent list, select the MediaAgent that will write the data to the storage.

     Note

     The list displays MediaAgents classified as Active (MediaAgents having license) and Inactive (MediaAgents having MediaAgent package installed, but license not consumed). The license is auto consumed if you select an inactive MediaAgent.

   - To install a new MediaAgent, click the plus + sign.

     The Install MediaAgent dialog box appears. Add the following information:

     1. In the Host name box, type the complete host name of the computer where you have to install the MediaAgent.

     2. In the User name box, type the credentials required to login to the computer where you want to install the MediaAgent.

     3. In the Password box, type the password required to login to the computer where you want to install the MediaAgent.

     4. Select the OS Type for the MediaAgent.

     5. Optional: To override the default installation path, in the Installation location box, type the new path.

     6. Move the Reboot if required toggle key to the right, to automatically reboot the MediaAgent computer after installing the MediaAgent software.

     7. Click Install.

     Once the MediaAgent software is installed, it will be visible in the MediaAgent list.

5. Enter the backup location and other fields that appear based on the host MediaAgent selected.

   Review the additional information and notes below for help.

6. Click Save.

The new location will be listed in the Backup locations section.

## Result

The backup is created and associated with the selected MediaAgents.

If shared paths are configured, the associated MediaAgents use those paths to access the backup location. Shared paths enable multiple MediaAgents running different operating systems or using different path formats to access the same storage location.

## Additional Information

The backup location path is entered from the perspective of the selected host MediaAgent.

### Scenario 1: Single Windows MediaAgent

When only one Windows MediaAgent is previously associated with the disk storage:

#### Local Backup Location

The following field is displayed:

- Backup Location

  For example: `E:\Backups`

- Windows Shared Path

  - Credential

  - Path

    Format: `\\<hostMediaAgent>\Backups`

    For example: `\\WinMA1\Backups`

#### Network Backup Location

The following fields are displayed:

- Credential

- Backup Location

  For example: `\\WinMA1\Backups`

Shared path fields are not displayed.

### Scenario 2: Multiple Windows MediaAgents

When multiple Windows MediaAgents are previously associated with the disk storage and a Windows MediaAgent is selected as the host:

#### Local Backup Location

The following fields are displayed:

- Backup Location

  For example: `E:\Backups`

- Windows Shared Path

  - Credential

  - Path

    Format: `\\<hostMediaAgent>\Backups`

    For example: `\\WinMA1\Backups`

#### Network

- Credential

- Backup Location

  Format: `\\StorageMachineName\Backups`

  For example: `\\WinMA2\Backups`

All Windows MediaAgents except the selected host MediaAgent use the Windows shared path to access the backup location.

### Scenario 3: Unix-Only MediaAgents (one or multiple)

When only Unix MediaAgents are previously associated with the disk storage and a Unix MediaAgent is selected as the host:

#### Local Backup Location

The following field is displayed:

- Backup Location

  For example: `/MountedLibrary/folder1`

- Unix Shared Path

  - Path: This is the path where Windows shared path is mounted that allows access to Unix MediaAgents.

    For example: `/MountedLibrary/folder1`

When multiple Unix-only MediaAgents are previously associated with the disk storage, configure a Unix shared path to enable the additional MediaAgents to access the backup location.

### Scenario 4: Mixed Windows and Unix MediaAgents (Windows Host)

When both Windows and Unix MediaAgents are previously associated with the disk storage and a Windows MediaAgent is selected as the host:

#### Local Backup Location

The following fields are displayed:

- Backup Location

  For example: `E:\Backups`

- Windows Shared Path (appears when there is more than one Windows MediaAgent)

  - Credential

  - Path

    For example: `\\WinMA1\Backups`

- Unix Shared Path

  - Path: This is the path where Windows shared path is mounted that allows access to Unix MediaAgents.

    For example: `/MountedLibrary/folder1`

The Windows shared path is used by the additional Windows MediaAgents.

#### Network

- Credential

- Backup Location

  Format: `\\StorageMachineName\Backups`

  For example: `\\WinMA2\Backups`

- Unix Shared Path

  - Path: This is the path where Windows shared path is mounted that allows access to Unix MediaAgents.

    For example: `/MountedLibrary/folder1`

### Scenario 5: Mixed Windows and Unix MediaAgents (Unix Host)

When both Windows and Unix MediaAgents are previously associated with the disk storage and a Unix MediaAgent is selected as the host:

The following fields are displayed:

- Backup Location

  For example: `/MountedLibrary/folder1`

- Windows Shared Path

  - Credential

  - Path

    For example: `\\WinMA1\Backups`

- Unix Shared Path

  - Path: This is the path where Windows shared path is mounted that allows access to Unix MediaAgents.

    For example: `/MountedLibrary/folder1`

The Windows shared path is used by the Windows MediaAgents.

Notes

- Ensure that all selected MediaAgents can access the backup location.
- All shared paths must point to the same physical storage location.
- Validate access to the backup location from each MediaAgent.
