Patent number: 10747719Abstract: Systems and methods for restoring a file system to a point-in-time without relying on a backup. One system includes an electronic processor configured to automatically restore a file system to a specified point-in-time by (a) automatically restoring, from a recycle bin, items deleted from the file system after the point-in-time, (b) automatically deleting, from the file system, items created within the file system after the point-in-time, (c) automatically moving items moved within the file system after the point-in-time to a location within the file system associated with the point-in-time, (d) automatically deleting, from the file system, items copied within the file system after the point-in-time, (e) automatically renaming items renamed within the file system after the point-in-time to a name associated with the point-in-time, and (f) automatically restoring, from a version history, a version associated with the point-in-time for items with content modified after the point-in-time.Type: GrantFiled: December 8, 2017Date of Patent: August 18, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Jose A. Barreto, Clement B. Fauchere, Meir E. Abergel, Steven J. Rayson, Jiashan Song, Andrew Sean Watson, Shaun W. Kimber, Ronakkumar N. Desai, Andrew Glover

Patent number: 10664170Abstract: Variety of approaches to provide partial storage of large files in distinct storage systems are described. A storage service initiates operations to provide storage of large files by determining a rapid access portion and a slow access portion of a file. The rapid access portion of the file is stored in a rapid access storage system and the slow access portion of the file (or an entirety of the file) is stored in a slow access storage system. In response to an access request to the file, the rapid access portion of the file is provided from the rapid access storage system. Next, the slow access portion of the file is retrieved from the slow access storage system to be provided while providing the rapid access portion of the file.Type: GrantFiled: December 14, 2016Date of Patent: May 26, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Andrew K. Glover, Jose A. Barreto, Ronakkumar N. Desai

Patent number: 9785666Abstract: The subject disclosure is directed towards a data deduplication technology in which a hash index service's index is partitioned into subspace indexes, with less than the entire hash index service's index cached to save memory. The subspace index is accessed to determine whether a data chunk already exists or needs to be indexed and stored. The index may be divided into subspaces based on criteria associated with the data to index, such as file type, data type, time of last usage, and so on. Also described is subspace reconciliation, in which duplicate entries in subspaces are detected so as to remove entries and chunks from the deduplication system. Subspace reconciliation may be performed at off-peak time, when more system resources are available, and may be interrupted if resources are needed. Subspaces to reconcile may be based on similarity, including via similarity of signatures that each compactly represents the subspace's hashes.Type: GrantFiled: July 13, 2015Date of Patent: October 10, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Jin Li, Sudipta Sengupta, Ran Kalach, Ronakkumar N.

Patent number: 9449016Abstract: Techniques for data synchronization policies are described. In one or more implementations, techniques may be employed to set data synchronization (“sync”) policies for devices in a data sync environment. The sync policies specify parameters for sync operations in the sync environment, such as how frequently data sync operations are performed, what types of data are synced to particular devices, how frequently particular types of data are synced, and so on. In implementations, the sync policies consider the number of devices that are participating in a sync environment and attributes of the devices in specifying parameters for sync operations. Data can be synchronized among devices in the sync environment based on the sync policies.Type: GrantFiled: September 9, 2011Date of Patent: September 20, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Gyorgy K. Schadt, John E. Brezak, David A. Nichols, Oded Y. Shekel, Albert Hwang, Patrick R. Jakubowski, Ronakkumar N. Desai

Patent number: 9053032Abstract: The subject disclosure is directed towards a data deduplication technology in which a hash index service's index maintains a hash index in a secondary storage device such as a hard drive, along with a compact index table and look-ahead cache in RAM that operate to reduce the I/O to access the secondary storage device during deduplication operations. Also described is a session cache for maintaining data during a deduplication session, and encoding of a read-only compact index table for efficiency.Type: GrantFiled: December 28, 2010Date of Patent: June 9, 2015Assignee: Microsoft Technology Licensing, LLCInventors: Sudipta Sengupta, Biplob Debnath, Jin Li, Ronakkumar N.
