Bandwidth Congestion with Copy Recovery Point to Cloud Jobs

Symptom

Running Copy Recovery Points (CRP) jobs often result in slowing down of agent machine due to bandwidth congestion.

Solution

Arcserve helps you define a specific bandwidth for CRP jobs. As a result, even if the machine has multiple jobs running, with CRP jobs, bandwidth is controlled automatically on the agent machine only for CRP jobs. Using a separate process AFCRPBackend.exe for CRP jobs, you can configure the Policy based QoS to AFCRPBackend.exe and throttle the outbound bandwidth.

Follow these steps:

  1. Type MMC in Start box and press Enter.
  2. Microsoft Management Console opens.
  3. From the MMC console, press CTRL+M.
  4. Add or Remove Snap-ins dialog appears.
  5. From the Add or Remote Snap-ins dialog, select Group Policy Object Editor under Available snap-ins and click Add.
  6. In the Select Group Policy Object dialog, leave the default setting of Local Computer and click Finish.
  7. Click OK.
  8. The Add or Remote Snap-ins dialog closes.
  9. From the left pane of the MMC console Window, expand Local Computer, Computer Configuration, Windows Settings, and right click Policy-based QoS and select Create new policy from the menu.
  10. In the policy-based QOS windows perform the following options, and click Next:
  11. - Enter a name for the new policy.
  12. - Set the DSCP value to 0.
  13. - Select the check box of Specify Outbound Throttle Rate.
  14. Note: We recommend selecting MBps as option.
  15. For QoS policy applies to, select the check box of Only applications with this executable name and enter the following exe path, and click Next:
  16. C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\AFCRPBackend.exe
  17. Note: AFCRPBackend.exe helps ensure that bandwidth restriction is applicable only to CRP jobs even if multiple jobs are running on the agent machine.
  18. Proceed with default settings to the last screen and click Finish.
