Solution:

To successfully back up a Hyper-V VM with checkpoints, you can follow one of the solutions below:

Solution 1: Upgrading BDRShield Backup Server

1. Upgrade your BDRShield Backup Server to version 4.1.0 or a later release. Refer to the BDRShield Software Update Guide for detailed instructions on the upgrade process.

2. Upgrade your Windows Hyper-V Host machine (the host being backed up) to Windows 2016 or a newer version.

1. Open Hyper-V Manager and select the virtual machine for which you want to delete checkpoints.

2. In the Checkpoints section, right-click on the checkpoint you wish to delete and select "Delete."

3. If you want to delete a checkpoint and all subsequent checkpoints, right-click on the earliest checkpoint and choose "Delete Checkpoint Subtree."

4. Confirm the deletion in the Delete Confirmation dialog box and click "Delete."

5. After deleting the checkpoints, the backup job will resume its regular schedule, or you can manually initiate the backup job by clicking on the "Run now" option.

6. It is recommended to restart the VM after deleting the checkpoint.

Note:

The action of "Delete" for checkpoints cannot be reversed. Please exercise caution when deleting checkpoints to avoid data loss.
