CommVault Assigned Four Patents

Retaining and using data block signatures in data protection operations
CommVault Systems, Inc., Oceanport, NJ, has been assigned a patent (8,578,109) developed by Manoj Kumar Vijayan, and Deepak Raghunath Attarde, Marlboro, NJ, for “systems and methods for retaining and using data block signatures in data protection operations.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system according to certain embodiments associates a signature value corresponding to a data block with one or more data blocks and a reference to the data block to form a signature/data word corresponding to the data block. The system further logically organizes the signature/data words into a plurality of files each comprising at least one signature/data word such that the signature values are embedded in the respective file. The system according to certain embodiments reads a previously stored signature value corresponding to a respective data block for sending from a backup storage system having at least one memory device to a secondary storage system. Based on an indication as to whether the data block is already stored on the secondary storage system, the system reads the data block from the at least one memory device for sending to the secondary storage system if the data block exists on the secondary storage system, wherein the signature value and not the data block is read from the at least one memory device if the data block exists on the secondary storage system.”

The patent application was filed on Dec. 30, 2010 (12/982,100).

Performing storage operations in cloud storage environment
CommVault Systems, Oceanport, NJ, has been assigned a patent (8,612,439) developed by five co-inventors for “performing storage operations in a cloud storage environment, including searching, encryption and indexing.”

The co-inventors are Anand Prahlad, Bangalore, India, Rajiv Kottomtharayil, Marlboro Township, NJ, Srinivas Kavuri, Hyderabad, India, Parag Gokhale, Ocean, NJ, and Manoj Vijayan, Marlboro Township, NJ.

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods are disclosed for performing data storage operations, including content-indexing, containerized deduplication, and policy-driven storage, within a cloud environment. The systems support a variety of clients and cloud storage sites that may connect to the system in a cloud environment that requires data transfer over wide area networks, such as the Internet, which may have appreciable latency and/or packet loss, using various network protocols, including HTTP and FTP. Methods are disclosed for content indexing data stored within a cloud environment to facilitate later searching, including collaborative searching. Methods are also disclosed for performing containerized deduplication to reduce the strain on a system namespace, effectuate cost savings, etc. Methods are disclosed for identifying suitable storage locations, including suitable cloud storage sites, for data files subject to a storage policy. Further, systems and methods for providing a cloud gateway and a scalable data object store within a cloud environment are disclosed, along with other features.”

The patent application was filed on March 31, 2010 (12/751,713).

Block-level single instancing
CommVault Systems, Oceanport, NJ, has been assigned a patent (8,578,120) developed by Deepak R. Attarde, Ocean, NJ, Rajiv Kottomtharayil, Marlboro, NJ, and Manoj K. Vijayan, 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 Dec. 28, 2009 (12/647,906).

Performing storage operations using NAS
CommVault Systems, Oceanport, NJ, has been assigned a patent (8,577,844) developed by Anand Prahlad, East Brunswick, NJ, and Jeremy Schwartz, Red Bank, NJ, for “systems and methods for performing storage operations using NAS.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: “Systems and methods for performing hierarchical storage operations on electronic data in a computer network are provided. In one embodiment, the present invention may store electronic data from a network device to a network attached storage (NAS) device pursuant to certain storage criteria. The data stored on the NAS may be migrated to a secondary storage and a stub file having a pointer pointing to the secondary storage may be put at the location the data was previously stored on the NAS. The stub file may redirect the network device to the secondary storage if a read request for the data is received from the network device”

The patent application was filed on Sept. 7, 2012 (13/607,561).
