Modifying Data Domain System settings

You can modify the username, password, stream limit, or block size for an existing Data Domain system.

Click Update, and in the Update Device Details dialog box, modify the required settings.


Specify a DD Boost user account that can be used to log on to the device for backups and restores. Verify that the user account is created on the Data Domain system before you add the device to the NetVault Backup Server.


Type the password for the user account.

Stream Limit

The default value for this setting is 32 streams. This setting applies to all NetVault Backup Servers to which the container is added. If the number of data streams exceeds the defined limit for the container, the Media Manager reports an error (“Device has too many streams”).

You can set the soft stream limit to any value between 1 and 256.

If the container is added to more than one NetVault Backup Server, set the same soft stream limit on all servers.

Block size

Type or select the block size for data transfers. The block size is specified in KiB. The default block size is 128 KiB.

Click Update the save the settings.

Checking the status of a disk-based storage device

Click Check, and then in the confirmation dialog box, click Check again.

Changing the status of a disk-based storage device

If the device is offline, click Online to bring it back online.
If the device is online, click Offline to take it offline.
The Offline method marks the device as offline and makes the device unavailable to NetVault Backup. This method does not physically take the system offline.

Scanning a disk-based storage device

You can use the Scan method to query all backups stored on a disk-based storage device and import those backups that are not indexed in the given NetVault Backup Server’s database.

To import backups to the database, the NetVault Backup Server must have the same NetVault Backup Machine Name as the original server that performed the backups. The amount of time it takes to scan the backups depends on the number of backups that need to be imported and the size of the backup indexes.

You can scan indexes that are generated with the same or previous versions of NetVault Backup. You cannot scan indexes generated with a newer version of NetVault Backup on an earlier version of the server if the servers do not use the same index version. If an index version is not supported, the index is not imported and a message is generated in the logs.

In the Navigation pane, click Manage Devices. In the list of devices, locate the device, and click the corresponding Manage Device icon.
Alternatively, in the Navigation pane, click Explore Storage. Click Explore Disk Storage, and in the repository table, select the device.
On the RAS Device Management or Explore Disk Storage page, click Scan.
In the Scan Device dialog box, you can configure the following option:
Minimum life for imported backups: This option specifies the minimum life for backups that are imported to the NetVault Database. This option only applies to the backups that are not available in the NetVault Database.
Click Scan to start the scanning process and close the dialog box.
