I'm using Veeam B&R 6.1 to backup our vSphere VM's, but all backups are failing with the error:
Code: Select all
Failed to prepare guest for hot backup. Error: Failed to connect to guest agent. Errors: 'Cannot connect to the host's administrative share. Host: [xx.xx.xx.xx]. Account: [xxx\xxx]. Win32 error:The network path was not found. Code: 53
Network-less interaction with Microsoft Windows guests having UAC enabled (Vista or later) requires that Local Administrator (MACHINE\Administrator) or Domain Administrator (DOMAIN\Administrator) account is provided on Guest Processing step.
Our backup servers only have a connection to vSphere and storage. They can't access the guest networks. Also, due to security reasons, the 'default' DOMAIN\Administrator account is disabled so I entered another domain administrator account. Is there any way to enable Application-aware backups without disabling UAC or altering the reg key HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\system\LocalAccountTokenFilterPolicy?
