    Abstract: An illustrative data storage system is configured to use pods to efficiently copy files systems constructed of block objects. In certain examples, the storage system generates, based on a pod that includes a file system constructed of block objects, a virtual copy of the pod such that modifications made to the pod (e.g., modifications to contents of the block objects by way of the pod) after the generation of the virtual copy of the pod are distinct from the virtual copy of the pod. In certain examples, the virtual copy of the pod is a writeable clone of the pod and modifications made to the clone (e.g., modifications to contents of the block objects by way of the clone) after the generation of the clone are distinct from the pod.

    Abstract: An illustrative system is configured to optimize a transfer of a file system from a source storage system to a target storage system. For example, the system, in association with the transfer, determines that a copy of a collection of blocks containing data of block objects of the file system is already stored at the target storage system. In certain examples, an identifier referencing the collection of blocks is shared by the source and target storage systems and is used to determine that the copy of the collection of blocks containing data of block objects of the file system is already stored at the target storage system. The system uses the copy of the collection of blocks already stored at the target storage system instead of transferring the collection of blocks from the source storage system to the target storage system as part of the transfer.

    Abstract: Space reporting in a storage system, including: determining, for one or more system-visible objects in the storage system, an amount of physical space consumed by each system-visible object and an amount of logical space consumed by each system-visible object; identifying, for each of the one or more system-visible objects in the storage system, one or more user-visible objects that reference the system-visible object; determining, for each of the one or more user-visible objects, an amount of physical space consumed by the user-visible object in dependence upon the amount of physical space consumed by each system-visible object referenced by the user-visible object; and determining, for each of the one or more user-visible objects, an amount of logical space consumed by the user-visible object in dependence upon the amount of logical space consumed by each system-visible object referenced by the user-visible object.
