When performing a Hyper-V VM backup, the following error message is displayed on the backup client interface, or in the backup report:
|*||info||...||Start running pre-commands|
|*||info||...||Finished running pre-commands|
Failed to take VM recovery checkpoint. Error = Object reference not set to an instance of
an object., vm: virtual_machine_id
This issue can occur if the affected virtual machine is being backup by multiple backup sets that run at the same time (e.g. overlapping backup jobs of multiple backup sets).
To resolve the issue, patch the AhsayOBM application to version 220.127.116.11 or above. The instructions can be found by Clicking Here.
