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.
