Disable Rescan of HBA Adapters During Incremental Backup

Applicable for VMware ESX

Symptom

When the source node and the proxy server are in different VMware ESX servers, and I run an Incremental backup, my backup takes a longer time to run. I also receive multiple rescan messages. I want to disable the rescanning of all host bus adapter (hba) of other VMware ESX servers during Incremental backups.

Solution

You can disable the scan by creating a registry key in the proxy server and assigning a value to it.

Follow these steps:

  1. Log in to the machine.
  2. Navigate to the following folder: 
    HKEY_LOCAL_MACHINE\SOFTWARE\Arcserve\Unified Data Protection\Engine
  3. Create the following registry key (DWORD), if it is not already created 
    DisableAllESXNodeRescan
  4. Set the value of the registry key to 1.
