Abstract: Technology is disclosed for backing up data to and recovering data from a destination storage system that stores data in a format different form that of a primary storage system (“the technology”). A replication stream having the data of multiple files, metadata of the files, and reference maps including a mapping of the corresponding file to a portion of the data of the corresponding file is generated at the primary storage system. The replication stream is sent to a parser to map or convert the data, the files, and the reference maps to multiple storage objects in a format the destination storage system is configured to store. Various types of storage objects are generated, including a first type of the storage objects having the data, a second type of storage objects storing the reference maps, and a third type of the storage objects storing metadata of the files.

Abstract: A client identifies a first data unit to be shared from a first file to a second file and sends an operation to copy that indicates the first data unit to be shared. The operation to copy the first data unit from the first file to the second file is received. In response to receiving the operation to copy the first data unit from the first file to the second file, it is determined whether the first data unit can be shared with the second file. In response to determining that the first data unit cannot be shared with the second file, the first data unit is copied to the second file. In response to determining that the first data unit can be shared with the second file, the first data unit is shared between the first file and the second file.

Abstract: A request is received to retrieve at least a portion of a file from a compressed data archived image stored in a backup storage device. The compressed data archived image comprises a backup of a file system having a number of directories and a number of files. The compressed data archived image comprises a file that includes a compression of the number of files. An address of the at least the portion of the file within the compressed data archived image is determined. The at least the portion of the file is retrieved at the address in the compressed data archived image, without decompressing the compressed data archived image.

Abstract: Examples described herein include a data migration system for migrating data between different data storage environments. The data migration system creates a first volume on a first storage system, and creates a logical unit within the first volume. The data migration system then creates a virtual volume on a virtual storage system associated with a second storage system, wherein data stored in the virtual volume is backed by the logical unit on the first storage system. The data migration system then replicates, on the virtual volume, a set of data stored on the second storage system. Upon replicating the set of data onto the virtual volume the virtual storage system may automatically create a copy of the corresponding data in the logical unit of the first volume.

Abstract: A method and system for replicating file system entities in a manner that preserves block-level access and file system efficiency mechanisms such as deduplication are disclosed. In an embodiment, a replication engine receives a stream of file system entities that include a file system inodes and file system data blocks. The replication engine generates object-based storage (OBS) objects based on data and reference information specified by the file system entities. As part of generating the OBS objects, the replication engine generates at least one inode file object that associates file block numbers of a file system inode file and the inode numbers. The replication engine uses inode information to generate reference objects that logically associate file block numbers with data block numbers in per inode manner. The replication engine further generates data objects that contains the file system data blocks and that associates the data blocks with corresponding data block numbers.

Abstract: An enterprise may use file level and block level storage for operational access to reap the performance benefits, and use object storage for back-up storage and scale out. Data of objects and objects themselves can be organized to allow for efficient storage management operations, including storage snapshot operations and deduplication operations. A root file container can be represented in object storage with a metadata object (“file container object”) and child file container can be represented in object storage with a metadata object (“file group object”). Each file can be represented in object storage with a metadata object that indicates the data units of the file depending upon the storage technology hosting the file (e.g., a file data block in file level storage). The data units of the file can be represented in object storage as elements of a data object.
