Abstract: An illustrative data storage system is configured to replicate, from a source storage system to a target storage system, a pod that includes a file system constructed of block objects. The pod may be a storage system construct that groups storage entities within a namespace and supports operations on the storage entities as a group. The block objects may store metadata for individual files and directories of the file system and may support random read-write access to blocks of data associated with the files and directories of the file system.
