Abstract
A method, computer readable medium, and a system for reconstituting a virtual snapshot of files in a file virtualization system includes forming at a file virtualization device a virtual snapshot that includes a plurality of physical snapshots associated with one or more file storage devices participating in the virtual snapshot, receiving a request for performing an operation on one or more physical snapshots in the plurality of physical snapshots, providing the one or more physical snapshots in response to the request for performing the operation when the one or more physical snapshots exists in the virtual snapshot, and reconstituting the virtual snapshot by including the one or more physical snapshots to form a reconstituted virtual snapshot in response to the request for performing the operation when the one or more physical snapshots do not exist in the virtual snapshot.
