    Abstract: A versioned file system comprises a set of structured data representations. At a first time, an interface creates and exports to a cloud data store a first structured data representation corresponding to a first version of the local file system. The first structured data representation is an XML tree having a root element, one or more directory elements associated with the root element, and one or more file elements associated with a given directory element. Upon a change within the file system, the interface creates and exports a second structured data representation corresponding to a second version of the file system. The second structured data representation differs from the first structured data representation up to and including the root element of the second structured data representation. The interface continues to generate and export the structured data representations to the data store.

  • Patent number: 11561695
    Abstract: In a storage system such as a SAN, NAS, or storage array that implements hierarchical performance tiers based rated drive access latency, on-drive compression is used on data stored on a first tier and off-drive compression is used on data stored on a second tier. Off-drive compression is more processor intensive and may introduce some data access latency but reduces storage requirements. On-drive compression is performed at or near line speed but generally yields lower size reduction ratios than off-drive compression. On-drive compression may be implemented at a higher performance tier whereas off-drive compression may be implemented at a lower performance tier. Further, space saving realized from on-drive compression may be applied to over-provisioning.

The files are stored in a storage service accessible via a network, and a separate copy of each file can be shared with each student in the class. In order to facilitate the sharing of multiple copies of the file, a share pool is created in a partition of the storage service allocated to the instructor. The share pool includes a number of stub files that are placeholders for clones of the shared file. A share handler service receives a request to share a file with a class, requests a number of stub files from the share pool, and utilizes the number of stub files to generate clones of the shared file in the partition of the storage service. Students are then granted access to the clones in the partition.

  • Patent number: 11360852
    Abstract: Methods and apparatus for selection of memory devices in a distributed storage network. In an embodiment, a computing device receives a data object for storage and forwards the data object to a buffer for temporary storage, the buffer comprised of a first memory devices of a first memory type. A system level storage efficiency is determined for the data object based, at least in part, on a data attribute associated with the data object. Second memory devices, of a second memory type, are selected based on the system level storage efficiency preference, and compatible dispersed storage error encoding parameters for the data object are determined. The data object is encoded using the encoding parameters to generate a plurality of encoded data slices, which are provided to the second plurality of memory devices for storage. Further, system addressing information is generated based on an identifier associated with the data object.
