VSS_E_UNSUPPORTED_CONTEXT
VSS_E_UNSUPPORTED_CONTEXT means that the selected provider cannot create the requested type of shadow copy. A VSS context controls characteristics such as persistence, client accessibility, transportability, and backup semantics.
How to investigate for VSS_E_UNSUPPORTED_CONTEXT
- Identify the context flags requested by the backup or management application.
- Check the selected provider's supported snapshot types and storage requirements.
- Use a compatible context or provider instead of assuming that all providers support every VSS scenario.

Evidence to capture
- Capture any IErrorInfo text, activity identifier, event-log entry, and subsystem trace that mentions this result or the vss / context operation.
- check the documented return contract of the specific API because the same HRESULT can require different recovery in different interfaces.
