Configuring Disk Storage

You can configure disk storage and define the backup locations which can be accessed by multiple cross-platform clients and backup gateways for writing the data.

The number of partitions created is determined by the number of DDB backup gateways selected during configuration:

• 1 backup gateway selected

  • Two partitions are created on the single MediaAgent.

• 2 backup gateways selected

  • Two partitions are created on each backup gateway, for a total of four partitions.

• 3 to 6 backup gateways selected

  • A total of six partitions are created and distributed evenly across the selected backup gateways.

• More than 6 backup gateways selected

  • The first six backup gateways are used to create the six partitions.

  • The remaining backup gateways are assigned the Deduplication Database (DDB) role only.

The software automatically assigns the deduplication database (DDB) path on the backup gateway without requiring user input.

Before You Begin

Install a Commvault Cloud backup gateway on an on-prem server. For more information, see On-Premises Deployment of a Commvault Cloud Backup Gateway.

Procedure

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

   The Disk page appears.

2. In the upper-right corner of the page, click Add.

   The Add disk dialog box appears.

3. In the Name box, type a name for the disk storage.

4. In the Backup locations section, click Add.

   The Add Backup location dialog box appears.

   1. From the MediaAgent list, select the backup gateway that will write the data to the storage.

      Note

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

   2. To set the disk access path, use one of the following options:

      • To use a local disk as the disk access path, click Local.

      • To use a network drive as the disk access path, click Network and then enter the User name and Password needed to access the backup location.

        To use a pre-defined credential, move the Use saved credentials toggle key to the right, and then select the pre-defined credential from the Name list.

        To add a new credential, click the + sign to create new credentials to access a network drive as described in Creating a Credential to Access a Network Drive.

   3. In the Backup location box, type the full path name to the storage location.

   4. Click Add.

5. Verify that the Use Deduplication toggle is enabled to use deduplication for data stored in the storage.

6. From the DDB MediaAgent list, select one or more backup gateways to use for deduplication.

7. To add a DDB backup gateway, click the Add icon.

   The Install MediaAgent dialog box appears.

   For instructions to add a backup gateway, see Installing a MediaAgent.

8. Click Save.
