Error description
The current ANS5257E message is documented as the following : ANS5257E The volume 'volume' does not support the requested VSS operation. Explanation: The volume does not support the requested VSS operation. Some reasons for this error include: * For off-load backup requests, a hardware provider cannot be found * For off-load backup requests, the provider does not support transportable media * For local backup requests, the provider does not support persistent snapshots System action: Processing stops. User response: Retry the request using a supported backup destination. In the 'Explanation' section, a fourth possible cause should be added to include the case when the snapshot operation is not supported for the current volume with the option VSSUSESYSTEMPROVIDER YES. In that case, the 'User response' section should also suggest to retry the operation with the option VSSUSESYSTEMPROVIDER NO. One example were this may apply is for Hyper-V guest backups. The message ANS5257E The volume '\\<hostname>\<disk>$\<volume path and name>' does not support the requested VSS operation. will appear if the following conditions are met : 1. the volume is a Hyper-V cluster volume with a file system of type CSVFS (Cluster Storage Volume File System) 2. the option VSSUSESYSTEMPROVIDER is set to YES The error occurs because CSVFS volumes VSS snapshots need to be done using the Microsoft CSV Shadow Copy Provider instead of the Microsoft Software Shadow Copy provider. If VSSUSESYSTEMPROVIDER is set to YES, the client explicitly asks the operating system to use an unsupported VSS writer for the considered volume. In the above example, using the default 'VSSUSESYSTEMPROVIDER NO' will let the Operating System choose the appropriate provider and complete the operation successfully.
