ESXi Server error

Good morning,
I received this error message below related to a failed backup . What would be the best approach for this error?

“An error occurred while quiescing the virtual machine. See the virtual machine’s event log for details. An error occurred while saving the snapshot: Failed to quiesce the virtual machine. An error occurred while taking a snapshot: Failed to quiesce the virtual machine.”

[reply=“chris2525;d2288”] Did you check the event log on the virtual machine to see more about the error? I would check any event log entries for details and then have a look at this KB article for a possible solution: https://kb.msp360.com/standalone-backup/esxi-&-hyper-v/vm-quiescing-error
