A data storage system includes a generic snapshot interface, allowing for integration with a wide variety of snapshot-capable storage devices. The generic interface can be a programming interface (e.g., an application programming interface [API]). Using the snapshot interface, storage device vendors can integrate their particular snapshot technology with the data storage system. For instance, the data storage system can access a shared library of functions (e.g., a dynamically linked library [DLL]) provided by the vendor (or another by appropriate entity) and that complies with the specifications of the common programming interface. And by invoking the appropriate functions in the library, the data storage system implements the snapshot operation on the storage device.
