CommVault Assigned Four Patents

Performing data replication
CommVault Systems, Inc., Oceanport, NJ, has been assigned a patent (8,489,656) developed by Andrei Erofeev, Marlboro, NJ, for "systems and methods for performing data replication."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Preparing source data to be replicated in a continuous data replication environment. Certain systems and methods populate a file name database with entries having a unique file identifier descriptor (FID), short name and a FID of the parent directory of each directory or file on a source storage device. Such information is advantageously gathered during scanning of a live file system without requiring a snapshot of the source storage device. The database can be further used to generate absolute file names associated with data operations to be replayed on a destination storage device. Based on the obtained FIDs, certain embodiments can further combine write operations to be replayed on the destination storage device and/or avoid replicating temporary files to the destination system."

The patent application was filed on May 27, 2011 (13/118,250).

De-duplication for application-specific data
CommVault Systems, Inc., Oceanport, NJ, has been assigned a patent (8,484,162) developed by four co-inventors for "de-duplication systems and methods for application-specific data."

The co-inventors are Anand Prahlad, Bangalore, India, Manoj Kumar Vijayan, Rajiv Kottomtharayil, and Parag Gokhale, Marlboro, NJ.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "Content-aware systems and methods for improving de-duplication, or single instancing, in storage operations. In certain examples, backup agents on client devices parse application-specific data to identify data objects that are candidates for de-duplication. The backup agents can then insert markers or other indictors in the data that identify the location(s) of the particular data objects. Such markers can, in turn, assist a de-duplication manager to perform object-based de-duplication and increase the likelihood that like blocks within the data are identified and single instanced. In other examples, the agents can further determine if a data object of one file type can or should be single-instanced with a data object of a different file type. Such processing of data on the client side can provide for more efficient storage and back-end processing."

The patent application was filed on March 15, 2010 (12/724,292).

Management of media to and from media storage library
CommVault Systems, Inc., Oceanport, NJ, has been assigned a patent (8,484,165) developed by Parag Gokhale, Ocean, NJ, and Rajiv Kottomtharayil, Marlboro, NJ, for "systems and methods of media management, such as management of media to and from a media storage library."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system and method for determining media to be exported out of a media library is described. In some examples, the system determines a media component to be exported, determines the media component is in the media library for a specific process, and exports the media component after the process is completed."

The patent application was filed on March 31, 2008 (12/060,160).

Sharing media in computer network
CommVault Systems, Inc., Oceanport, NJ, has been assigned a patent (8,510,516) developed by six co-inventors for "systems and methods for sharing media in a computer network."

The co-inventors are Rajiv Kottomtharayil, Parag Gokhale, Ocean, NJ, Anand Prahlad, East Brunswick, NJ, Manoj Kumar, Ocean, NJ, David Ngo, Shrewsbury, NJ, and Varghese Devassy, Winnipeg, Canada.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A computerized method for sharing removable storage media in a network, the method comprising associating, in an index entry, a first piece of removable storage media in a first storage device with at least a first storage policy copy and a second storage policy copy; copying, to the first piece of removable storage media, data associated with the first storage policy copy; and copying, to the first piece of removable storage media, data associated with the second storage policy copy."

The patent application was filed on Sept. 14, 2012 (13/617,849).
