Problem Description

When performing a VMware ESXi/vCenter backup job in VDDK mode the following error message is shown in the backup log:

No.	Type	Timestamp	Log
*	...	...	...
*	erro	YYYY/MM/DD hh:mm:ss	Failed to create snapshot. [VmshGate.waitForSnapshot] Failed to create snapshot. Error=Snapshot not taken since the state of the virtual machine has not changed since the last snapshot operation."
*	info	...	...

Cause

The error message is returned by the VMware host, it is caused when a guest VM on the VMware ESXi/cCenter host machine is suspended and a snapshot is taken of the guest VM while it is in a suspended state using the vSphere snapshot manager.

This issue only occurs on VDDK/CBT mode backups, non-VDDK mode backup job work without this issue.

Resolution

There are two workarounds available to resolve this issue either:

Delete the current snapshot which was created after suspending the VM.
or
Switch the guest VM from a suspended state to power on state.
