Abstract
Methods, non-transitory computer readable media, and devices that more effectively manage snapshots by creating a namespace including files described by stored file recipe objects and each comprising fragments, directories described by metadata in the file recipe objects and each comprising one or more of the files, and snapshots described by stored snapshot request objects. Content of one of the directories are identified based on an identification of corresponding ones of the file recipe objects that existed within the namespace at a specified time. At least one of the files, included in the identified content and existing within the namespace at the specified time, is accessed in response to one or more received requests. A garbage collection operation is periodically performed to delete the recipe objects that are marked for deletion by tombstone objects and are unreferenced by any of the snapshots as determined based on the snapshot request objects.
