Create Data Deduplication Devices

To deduplicate data, create and choose a deduplication device group as the backup destination. When you create new deduplication devices, Arcserve Backup automatically assigns each device to a new deduplication device group.

You can create deduplication devices locally or remotely. When creating remote deduplication devices, you must manually specify security credentials by clicking the Security button on the Device Configuration dialog, as instructed in the following procedure, otherwise Arcserve Backup attempts to use the system account.

From Device Configuration, you can add one or more devices. Device Configuration verifies the validity of information specified for all devices and alerts you if a particular device failed verification.

To create data deduplication devices

  1. Open the Arcserve Backup Manager Console.

    From the Navigation Bar, expand Administration and click Device Configuration.

    The Device Configuration screen opens.

  2. Select Disk-based Devices and click Next.

    The Login Server screen opens.

  3. Specify the primary server name, authentication type, user name and password and then click Next.
  4. Specify the server on which the deduplication device is to be created and click Next. For local servers (default), you may browse and select a path. If you wish to specify a remote server, you must have administrator rights to that server and must manually type the path.

    The Disk-based Devices Configuration dialog opens.

  5. Click Add to access the Deduplication Devices list.

    Repeat this step as necessary to add more devices.

    Note: Arcserve Backup supports configuring an aggregate total of 255 FSDs and DDDs (only if the number of physical devices configured is 0).

  6. (Optional) If you specified remote path locations, click Security to provide login credentials.

    The Security dialog opens.

    Note: You must clear the Use Arcserve System Account (default) option to enable the security fields.

    Complete the required fields on the Security dialog and click OK.

    The Security dialog closes.

  7. Click Next on the Disk-based Devices Configuration dialog to continue.

    Arcserve Backup verifies the information specified for all devices in the list. If information is valid, the deduplication devices are added to the list. If any information is not valid, failed devices in the list are marked with a red Failed status. Click the corresponding Failed status to determine the cause of an individual error and resolve it. When all devices pass verification, a summary screen is displayed.

  8. Click Next to return to the Welcome to Device Configuration screen or click Exit to leave Device Configuration.

Important! When you create a deduplication device, the purge policy is automatically set to four weeks. That default purge policy is inherited by every job you set up for the device. If you wish to retain backups longer than four weeks, you must adjust the purge time when you submit the backup job.
