Hyper-V Agentless: How to backup using checkpoints only (4040035)

1. Open the Core Console and select the Hyper-V agentless machine you want to change..
2. Click on Settings and on menu to the left click Hyper-V.
3. Click and change Snapshot configuration to Do not create VSS snapshot during transfer, and click the checkmark to apply.

If you want to validate that the changes were properly applied and are working as expected you can do the following:

1. From the Hyper-V VM's Operative System, run the command vssadmin list shadows from an elevated Command Line window and you must not see any shadow create after the time that you enabled to option to only use checkpoints.
2. You can also validate the Windows Events\Application logs looking for VSS type events.
3. From the Hyper-V host you can review the Hyper-V VMMs-Admin events.
4. You can also validate directly from the Hyper-V Manager while a snapshot is being created, as per the below illustration.

For more details about the advantages and disadvantages of using Checkpoints instead of VSS Snapshots please refer to the following documentation from Microsoft:
