Agentless Restore (Microsoft Hyper-V)

You can use agentless restores to restore small files and folders into a virtual machine (VM) without installing an agent on the destination client. Agentless restores simplify deployment and reduce the impact of backup and restore operations for virtual machines that do not have high transaction rates and large data requirements. This option is preferred in cases in which the CommServe system or MediaAgent is not able to communicate with the VM (for example, in a restricted network).

Prerequisites

Note the following requirements for agentless restores:

  • The Hyper-V host must be running on a Windows 2012 R2 server operating system.
  • The destination VM must be running on Windows 2008 R2 with Service Pack 1 or later, or on later versions of the operating system such as Windows 2012 or Windows 2012 R2.
  • The destination VM must be powered on.
  • Make sure that the latest integration services are running on the destination VM.
  • Enable Guest file services on the destination VM. If not enabled, the restore operation will enable the services.

For instructions on running agent less restores, see Restoring Files and Folders to a VM without an Agent.

Considerations

  • A proxy cannot make two or more simultaneous parallel connections to the same VM. The restore to the VM for the job that establishes the first connection succeeds, but because an active connection exists between the proxy and the VM, subsequent jobs fail with a connection error.
  • The Restore ACLs option is not supported for agentless restores.

    As a workaround, you can use one of the following approaches:

    • Restore the file to the VSA proxy and then copy it to the VM.
    • Install a Windows File System Agent (restore-only) on the destination VM. During the restore, specify the destination folder as a UNC path pointing to the VM where the file should be restored.
