Patent number: 11853581Abstract: A request to restore a plurality of files to a first storage system from a backup stored at a second storage system is received. Corresponding file relocation metadata for each of the plurality of files is provided to the first storage system. The corresponding file relocation metadata for each of the plurality of files enables accessibility of contents of the plurality of files at the first storage system without storing entire contents of the plurality of files at the first storage system. A corresponding full content version for at least one of the plurality of files that is to be utilized by the first storage system is provided to enable direct access at the first storage system to contents of the at least one of the plurality of files instead of utilizing corresponding file relocation metadata for the at least one of the plurality of files to access the contents of the at least one of the plurality of files.Type: GrantFiled: June 14, 2022Date of Patent: December 26, 2023Assignee: Cohesity, Inc.Inventors: Nagapramod Mandagere, Yu-Shen Ng, Karandeep Singh Chawla
