Data.Disk.Swapper.Snapshot

Snapshot is a type class generalizing Serialize, as it, apart from writing values in the Put monad (or reading in Get), allows to perform arbitrary IO actions, like saving data to (or loading from) some external database files. Any instance of Serialize is also trivially an instance of Snapshot.
