The process of recovering virtual machines using the Recover VM recovery method may not let you retain the MAC addresses of the virtual machines (if a MAC address was defined) after the recovery process is complete. CA ARCserve Backup behaves in this manner in backup environments that use the VMware VDDK backup approach.

Note: The vSphere client application lets you verify whether the MAC address were retained after recovering virtual machines.

To configure the agent to retain MAC addresses after recovering VMs

  1. Log in to the computer where the agent is installed and open Windows Registry Editor.
  2. Browse to the following:
    HKEY_LOCAL_MACHINE\SOFTWARE\Computer Associates\CA ARCserve Backup\Client Agent\Parameters
  4. Create the following key:

    Key Name:


    Specify one of the following values for the key:

    • 1--Retain the MAC address
    • 0--Do not retain the MAC address
  5. Save the key and close Windows Registry Editor
