When performing a VMware ESXi/vCenter backup job in VDDK mode the following error message is shown in the backup 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."|
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.
There are two workarounds available to resolve this issue either:
VMware ESXi, vCenter, license, VDDK, suspend state, snapshot, CBT, power on state
