## Error messages

Message logs in the Management Console of the cloud failover appliance (CFA) show the following error:

VSS Snapshot Creation failed. Check Log file for more details.


## Error description

The VSS failure you see is due to insufficient storage space available to create the VSS snapshot.

The actual error message in the trace file is the following:

VSS_E_INSUFFICIENT_STORAGE


## Steps to resolve

Run systeminfo from the Support tab, and you can see the available resources for the server.

If this is a VM, you may be able to devote more system resources to that server and get away from the error.
