Patent number: 10089193Abstract: Systems and methods are provided which perform a file level restore by utilizing existing operating system components (e.g., file system drivers) that are natively installed on the target computing device. These components can be used to mount and/or interpret a secondary copy of the file system. For instance, the system can instantiate an interface object (e.g., a device node such as a pseudo device, device file or special file) on the target client which includes file system metadata corresponding to the backed up version of the file system. The interface provides a mechanism for the operating system to mount the secondary copy and perform file level access on the secondary copy, e.g., to restore one or more selected files.Type: GrantFiled: March 15, 2017Date of Patent: October 2, 2018Assignee: Commvault Systems, Inc.Inventors: Paramasivam Kumarasamy, Amit Mitkar, Andrei Erofeev, Durga Prasad Chedalavada, Suma Seshadri, Varghese Devassy
