Using metadata to enhance data identification operations
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,098,542) developed by Prahlad, Anand, Bangalore, India, Schwartz, Jeremy Alan, Austin, TX, Ngo, David, Brockway, Brian, Shrewsbury, NJ, and Muller, Marcus S., Granville, OH, for a “systems and methods for using metadata to enhance data identification operations.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Systems and methods for managing electronic data are disclosed. Various data management operations can be performed based on a metabase formed from metadata. Such metadata can be identified from an index of data interactions generated by a journaling module, and obtained from their associated data objects stored in one or more storage devices. In various embodiments, such processing of the index and storing of the metadata can facilitate, for example, enhanced data management operations, enhanced data identification operations, enhanced storage operations, data classification for organizing and storing the metadata, cataloging of metadata for the stored metadata, and/or user interfaces for managing data. In various embodiments, the metabase can be configured in different ways. For example, the metabase can be stored separately from the data objects so as to allow obtaining of information about the data objects without accessing the data objects or a data structure used by a file system.“

Application-aware and remote single instance data management
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,098,495) developed by Gokhale, Parag, Ocean, NJ, for a “application-aware and remote single instance data management.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and system for reducing storage requirements and speeding up storage operations by reducing the storage of redundant data includes receiving a request that identifies one or more files or data objects to which to apply a storage operation. For each file or data object, the storage system determines if the file or data object contains data that matches another file or data object to which the storage operation was previously applied, based on awareness of the application that created the data object. If the data objects do not match, then the storage system performs the storage operation in a usual manner. However, if the data objects do match, then the storage system may avoid performing the storage operation with respect to the particular file or data object.“

The patent application was filed on June 24, 2008 (12/145,347).

Utilizing snapshots for access to databases and applications
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,092,500) developed by Varadharajan, Prakash, Manalapan, NJ, Bansod, Ketan, South Amboy, NJ, Kumarasamy, Paramasivam, Morganville, NJ, Nallathambi, Vimal Kumar, Ocean City, NJ, and Vallabhaneni, Brahmaiah, Marlboro, NJ, for a “utilizing snapshots for access to databases and other applications.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and system for utilizing snapshots to provide copies of a database or other application or large data structure to computing devices receives a request for access to a copy of a database, and performs a snapshot of a storage volume containing the requested database. The system then clones the snapshot and mounts the snapshot to a computing device, thus enabling the computing device to access a copy of the database. In some examples, the system automatically updates copies of a database on a scheduled basis, (e.g., daily or weekly basis) to refresh a database regularly.“

Restoring computing environments
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,092,378) developed by Kumarasamy, Paramasivam, Morganville, NJ, and Mitkar, Amit, Neptune, NJ, for a “restoring computing environments, such as autorecovery of file systems at certain points in time.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A method and system for restoring a computing environment from a secondary data store, and facilitating such restoration, is described. In some examples, the system copies the configuration parameters of a computing environment, such as a file system, as well as the data within the file system, and transfers the copies to secondary storage for later restoration. For example, the system may generate an xml file of the configuration parameters of the computing environment when a backup operation of the computing environment is performed, and store the xml file along with copies of the data from the computing environment in secondary storage.“

Block-level single instancing
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,058,117) developed by Attarde, Deepak Raghunath, Kottomtharayil, Rajiv, and Vijayan, Manoj Kumar, Marlboro, NJ, for a “block-level single instancing.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Described in detail herein are systems and methods for single instancing blocks of data in a data storage system. For example, the data storage system may include multiple computing devices, e.g., client computing devices) that store primary data. The data storage system may also include a secondary storage computing device, a single instance database, and one or more storage devices that store copies of the primary data, (e.g., secondary copies, tertiary copies, etc.). The secondary storage computing device receives blocks of data from the computing devices and accesses the single instance database to determine whether the blocks of data are unique, (meaning that no instances of the blocks of data are stored on the storage devices). If a block of data is unique, the single instance database stores it on a storage device. If not, the secondary storage computing device can avoid storing the block of data on the storage devices.“

The patent application was filed on October 9, 2013 (14/049,463).

Managing replicated database data in dirty and clean shutdown states
CommVault Systems, Inc., Tinton Falls, NJ, has been assigned a patent (9,047,357) developed by Ngo, David, Shrewsbury, NJ, for a “systems and methods for managing replicated database data in dirty and clean shutdown states.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Systems and methods for replicating database data in a dirty shutdown state and generating copies of the replicated data in a clean shutdown state. For example, systems can include a tracking module, (e.g., a filter driver) that monitors transactions from a database application to a source database stored on a source storage device to generate log entries having at least one marker indicating a known good state of the application. The systems further include a computer coupled to a target storage device comprising a target database and log files. The computer processes the transactions, based on the log entries, to replicate data to a target database on the target storage device, performs a first snapshot on data stored in the target database existing in a dirty shutdown state, replays into the target database data stored in the log files to put the target database in a clean shutdown state, copies the target database in the clean shutdown state, and reverts the target database back to the dirty shutdown state in which the target database existed at the time of the first snapshot.“
