Issue



Deduplication storage folder or deduplication disk storage device may run low on disk space.

Mixed data / dedupe volumes may require the deduplication storage folder or deduplication disk storage device to be moved to a dedicated volume.


Solution



NOTE: This Technote does not apply to versions of Backup Exec prior to 2010 R3.  Earlier versions of Backup Exec did not support relocating the deduplication folder.  This Technote provides instructions for Backup Exec 2010 R3 and Backup Exec 2012 and above.

For Backup Exec 2010 R3 only:

  1. Open Backup Exec 2010 R3 Admin console
  2. Open the Devices tab
  3. Right click the Deduplication Storage Folder and select the Delete option.
NOTE: Jobs using the Deduplication Storage Folder as the destination device will need to be updated with a new device target. This can be done during the deletion of the Deduplication Storage Folder OR manually from the Job Setup tab.
  1. Stop Backup Exec Services.
NOTE: After the removal of the Deduplication Storage Folder, the Backup Exec Deduplication services should appear to be stopped and set to manual.
  1. Relocate the Deduplication Storage Folder to the new volume / path
  2. Start Backup Exec Services:
  3. Open Backup Exec 2010 R3 Admin console
  4. Open the Devices tab
  5. Right click on the Media Server name
  6. Select New Deduplication Storage Folder
  7. Supply the following information:
    1. Name – Should be the same device name for consistency, but not required.
    2. Storage Path – New volume / path
    3. Concurrent Operations – Defined as needed.
    4. Logon account – The same logon account used with previously.
  8. Click OK to start the Deduplication Storage Folder recreation process.

For Backup Exec 2012 and above only:

Scenarios:

  • Change the location of an existing deduplication disk storage device. 
  • Move the deduplication disk storage device to another volume on the same Backup Exec server.
  • If the Central Admin Server Option is installed, the deduplication disk storage device can be moved to another Backup Exec server.

NOTE: Symantec recommends using the same name for the deduplication disk storage device when changing the location, but it is not required.

Limitations:

  • If the Agent for VMware and Hyper-V is installed, the deduplication disk storage device cannot be moved to another Backup Exec server, but can be moved to another volume on the same Backup Exec server.
    • Refer to the section below “To change the location of a deduplication disk storage device” for more information.
  • If the Agent for VMware and Hyper-V is not installed, use the Configure Storage wizard to create a new deduplication disk storage device with a different name than the original.
    • Refer to the section below “To create a new deduplication disk storage device”  for more information.

Procedures:

To change the location of a deduplication disk storage device:

  1. Document the deduplication storage path by viewing the properties of the deduplication disk storage device.
  2. On the Storage tab, right-click the deduplication disk storage device, and then click Disable.
  3. Right-click the deduplication disk storage device again and then click Delete.
  4. When prompted to delete the device, click Yes.
  5. Retarget existing jobs when prompted, as needed.
  6. Click the Backup Exec button, select Configuration and Settings, select Backup Exec Services, and then click Stop all services.
  7. From Windows Explorer, copy the deduplication disk storage device to the new path or volume.
  8. In the Backup Exec Administration Console, click the Backup Exec button, select Configuration and Settings, select Backup Exec Services, and then click Start all services.
  9. On the Storage tab, click Configure Storage, click Disk-based storage, and then click Next.
  10. Click Deduplication disk storage, and then click Next.
  11. Enter a name and description for the deduplication disk storage device, and then click Next.
  12. Select a method to create the deduplication disk storage device.

NOTE: For a deduplication disk storage device that was created in Backup Exec version 2012, click Create a new deduplication disk storage device.

NOTE: For a deduplication disk storage device was created prior to Backup Exec version 2012, click Import an existing deduplication disk storage device, and then enter the path to the deduplication disk storage device.

  2. Specify the logon account that was used for original deduplication disk storage device, and then click Next.
  3. Select to enable encryption if required, and then click Next.
  4. Specify the number of concurrent operations that you want to let run on the deduplication disk storage device, and then click Next.
  5. Review the summary, and then click Finish.

To create a new deduplication disk storage device:

  1. On the Storage tab, click Configure Storage, click Disk-based storage, and then click Next.
  2. Click Deduplication disk storage, and then click Next.
  3. Enter a different name for the new deduplication disk storage device.
  4. Enter a description for the new deduplication disk storage device, and then click Next.
  5. Click Create a new deduplication disk storage device, and then click Next.
  6. Specify the logon account that was used for the original deduplication disk storage device, and then click Next.
  7. Select to enable encryption if required, and then click Next.
  8. Specify the number of concurrent operations that you want to let run on the deduplication disk storage device, and then click Next.
  9. Review the summary, and then click Finish.
  10. Restart Backup Exec services.

NOTES:

  • Time completion is affected by the number files in the deduplication storage folder or the deduplication disk storage device.
  • A deduplication folder or deduplication disk storage device can also be relocated to a different server using the same methodology as above.
  • The new media server or Backup Exec server must not already have a deduplication storage folder or deduplication disk storage device. Only one deduplication storage folder  or deduplication disk storage device is supported per media server or Backup Exec server. 
  • Do not use this technique to copy a deduplication storage folder or deduplication disk storage device to another server in a CASO environment and then attempt to use both deduplication devices.

If the deduplication storage folder or deduplication disk storage device fails to come online after service restart, contact the Backup Exec Technical Support team for assistance in resolving the issue.
