Abstract: Example embodiments relates to method and systems to restore content of a volume at a given point in time. A computing device to restore content of a volume at a given point in time comprises a physical processor and a machine-readable storage medium comprising machine readable instructions executable by the processor that cause the computing device to command a storage array to select a surviving snapshot that was created at a nearest point in time to the given point in time among a set of surviving read-only snapshots of content of the volume stored in the storage array, command the storage array to create an editable surviving snapshot of the selected surviving snapshot, perform a delta function associated with a deduplication system, the deduplication system comprising a set of backup objects for the set of surviving read-only snapshots and a set of backup objects for a set of non-surviving read-only snapshots of content of the volume and restore content of the volume at the given point in time by commanding the storage array to modify the editable surviving snapshot based on an output of the delta function. Each of the backup objects within the deduplication system comprises a manifest, the manifest comprising a list of chunk signatures that represents chunks of data. The delta function is performed between a manifest of a backup object of the selected surviving snapshot and a manifest of a backup object of a snapshot created at the given point in time.

Abstract: Storing and retrieving ciphertext in data storage can include determining a first ciphertext value for a first data chunk to be saved to a client-server data storage system using an encrypted chunk hash value associated with the first data chunk as an initial value, and storing the first data chunk on a server in the client-server data storage system in response to determining that the first ciphertext value is a unique ciphertext value. Also, storing and retrieving ciphertext in data storage can include decrypting a ciphertext value for a second data chunk received from a client in the client-server data storage system and based on an encrypted chunk hash value associated with the second data chunk, and sending the second data chunk to the client in response to determining that the decrypted ciphertext value corresponds to an original data chunk saved to the server by the client.

Abstract: In some examples, a local, non-tape based storage is to emulate tape storage elements at a first virtual tape library. A data structure associates first emulated tape storage elements of an emulated tape library with the storage elements in the first virtual tape library and associates second emulated tape storage elements of the emulated tape library with storage elements emulated by a remote storage in a second virtual tape library that is separate from the first virtual tape library, where the first virtual tape library is to present the emulated tape library that includes the storage elements of the first and second virtual tape libraries to a requesting entity that is separate from the first and second virtual tape libraries.
