Patent number: 8903774Abstract: Techniques to leverage replication to provide rolling point in time backup are described. Some embodiments are directed to techniques to provide rolling point in time backup with simplified restoration through distributed transactional re-creation. In one embodiment, for example, a technique may comprise creating a plurality of availability copies of a primary set of data; designating at least one of the plurality of availability copies as a backup copy; creating a log file that indicates changes to the primary set of data; updating the plurality of availability copies from the log file in near real time, without updating the backup copy; and restoring at least one of: the primary set of data and an availability copy using the backup copy and content resubmitted from a content contributor when an error occurs in at least one of: the primary set of data and an availability copy. Other embodiments are described and claimed.Type: GrantFiled: March 21, 2012Date of Patent: December 2, 2014Assignee: Microsoft CorporationInventors: Shuab Khan, Peter Byrne, Yogesh Bansal, Gregory Thiel, Ross Smith, IV

Publication number: 20140195489Abstract: Architecture that addresses an end-to-end solution for logical transactional replication from a shared-nothing clustered database management system, which uses adaptive cloning for high availability. This can be time based using a global logical timestamp. The disclosed architecture, used for refreshing stale clones, does not preserve user transaction boundaries, which is a more complex situation than where the boundaries are preserved. In such a scenario it is probable that for a given data segment no clone of the segment may contain the complete user transaction history, and hence, the history has to be pieced together from the logs of multiple different clones. This is accomplished such that log harvesting is coordinated with the clone state transitions to ensure the correctness of logical replication.Type: ApplicationFiled: January 21, 2014Publication date: July 10, 2014Applicant: MICROSOFT CORPORATIONInventors: Rui Wang, Michael E. Habben, Qun Guo, Peter Byrne, Robin D. Dhamankar, Vishal Kathuria, Mahesh K. Sreenivas, Yixue Zhu, Xiaowei Jiang

Patent number: 8612390Abstract: Searching cached log blocks. A method includes performing a first search on cached log blocks for a log block having a first log block ID. The log blocks are cached and organized into sequentially ordered log buffers in memory. Adjacent sequentially ordered log buffers are double linked to each other. Each log buffer includes a complete range of log blocks from a starting log block ID to an ending log block ID. As part of the first search one or more links are followed, forward and/or backward, to one or more other log buffers. The method may further include determining that the first log block is not found by following one or more links forward and/or backward to one or more other log buffers and as a result, follow one or more covering pointers to one or more log buffers to search for the first log block.Type: GrantFiled: May 2, 2011Date of Patent: December 17, 2013Assignee: Microsoft CorporationInventors: Rui Wang, Peter Byrne

Patent number: 8521695Abstract: The present invention relates to a system and method of data restoration, for instance, after the occurrence of a user error. In particular, snapshot database can be maintained that stores a copy of database data. The snapshot database does not have to store a complete copy of all data on a source database, but rather shares data that is common to both but not necessarily identical. If an error occurs on the primary database then the database can be reverted back to a point in time prior to the error by replacing source database files with snapshot files. Additionally, an undo component can be employed in conjunction with the snapshot to approach an error to a finer grained point in time. In brief, the present invention can restore a database much faster and simpler, while utilizing less space and resources than conventional data restoration technologies.Type: GrantFiled: December 28, 2011Date of Patent: August 27, 2013Assignee: Microsoft CorporationInventors: Michael J. Zwilling, Gregory A. Smith, Rajeev B. Rajan, Jakub Kulesza, Peter Byrne, Shashikant Brijmohan Khandelwal, Mark S. Wistrom

Patent number: 8078582Abstract: Aspects of the subject matter described herein relate to data change ordering in multi-log based replication. In aspects, local seeds are maintained for subtransactions involved in a transaction, where each subtransaction may occur on a different node that hosts one or more database fragments involved in the transaction. When a subtransaction communicates with another subtransaction in a transaction, the subtransaction sends its local seed to the other subtransaction. The receiving subtransaction compares its local seed with the received seed and updates its local seed if the received seed is logically after its local seed. A subtransaction uses a local seed to generate sequence identifiers for changes made by the subtransaction. These identifiers allow data changes of a transaction that are made on multiple nodes to be partially ordered relative to other changes made during the transaction.Type: GrantFiled: April 6, 2009Date of Patent: December 13, 2011Assignee: Microsoft CorporationInventors: Rui Wang, Peter Byrne, Leigh M.

Patent number: 7334002Abstract: The creation of multiple recoverable units within a database allows a database partition to be reconstructed during maintenance and disaster recovery operations. A method of creating a recovery unit includes partitioning a database into at least two recovery units. A primary catalog of metadata relating to the logical elements of a database such as tables, indexes, and file groups is created. A secondary catalog of metadata relating to the physical elements of a database such as pages, files, B-Trees, and log streams is created for each recovery unit. The primary and secondary metadata catalogs are linked such that only one log stream is associated with any one recovery unit. A single recovery unit may then be exercised to perform recovery or maintenance operations while the remaining recovery units of the database remain online.Type: GrantFiled: February 27, 2004Date of Patent: February 19, 2008Assignee: Microsoft CorporationInventor: Peter Byrne

Publication number: 20060206544Abstract: An automatic database backup and restoration system comprises an interface component that receives statements relating to backing up at least a portion of a first database, the original database resident upon a consumer computing device. A backup component associated with the interface component automatically copies at least the portion of the first database and writes the copied portion to a backup database, the backup database is a full backup of the first database. The consumer computing device can be, for example, one of a laptop computer, a desktop computer, a personal digital assistant, and a cellular phone.Type: ApplicationFiled: March 9, 2005Publication date: September 14, 2006Applicant: Microsoft CorporationInventors: Artem Oks, Martin Sleeman, Rajesh Iyer, Hanumantha Kodavalla, Peter Byrne, Steven Schmidt, Mark Wistrom, Rajeev Rajan

Publication number: 20040157335Abstract: The present invention relates to a method of testing an airbag module for a vehicle and, particularly, but not exclusively, to a method of testing an airbag module for a motor vehicle such as a car. A method of testing an airbag module is provided in which said module is tested for exposure to a given fluid, for example, water. The fluid exposure test ideally comprises the step of inspecting said airbag module or a swab taken therefrom by means of Atomic Absorption Spectroscopy techniques. The present invention thereby provides a testing method sufficiently rigorous to identify fluid damage potentially suffered by a previously installed airbag module during its service life.Type: ApplicationFiled: February 10, 2004Publication date: August 12, 2004Inventor: Peter Byrne
