Backing Up a UDP Appliance from Another Appliance Reports Duplicated Nodes

Symptom

When I back up Appliance B from Appliance A, I see the following warning message in the activity log:

"The following nodes are duplicated: Appliance_B, Appliance_A. As a result, they have the same agent identifier and may cause unexpected results. This duplicate node problem can be caused if the node was added using a different node name (such as the DNS name or IP address), or if some machines were set up by cloning from one to another."

Case 1, Appliance B is added as an RPS to the Appliance A UDP Console.

For example: from Appliance B, you can configure the appliance by using the UDP wizard and select "This appliance will function as an instance of Arcserve UDP Recovery Point Server managed by another Arcserve UDP console."

Solution

  1. Stop the data store in the Appliance B node from the RPS pane of the UDP console.
  2. Log in to Appliance B and delete the registry key of the Node ID that is located under [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine].
  3. Restart the Arcserve UDP Agent Web Service from the Appliance B node.
  4. Restart the Arcserve UDP RPS Data Store Service from the Appliance B node.
  5. From the UDP console, go to the Nodes, All Nodes pane and update the Appliance B node.
  6. Go to the Recovery Point Server pane and update the Appliance B node.
  7. Import the existing data store to the Appliance B RPS by setting it with the original backup destination.

Case 2: Appliance B is added only as an agent node to the Appliance A UDP console.

For example, a plan protects Appliance B by an agent-based backup task on the Appliance A UDP console.

  1. Log in to Appliance B and delete the registry key of the Node ID that is located under [HKEY_LOCAL_MACHINE\SOFTWARE\CA\ARCserve Unified Data Protection\Engine].
  2. Restart the Arcserve UDP Agent service from Appliance B.
  3. From the UDP console, go to the Nodes, All Nodes pane and update the node from Appliance B.
