ATTENTION 1st January, 2022: v7 officially End-of-Life [details] ===== 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.
