Summary: | A method, system, computer system, and computer program product are provided to quickly synchronize selected data, such as a single file, from two or more versions of the data stored on different storage volumes. Selected data are synchronized with a snapshot of the data stored on a different storage volume without copying all of the data and without copying the entire set of selected data. The present invention has minimal impact on performance of applications using the data having one or more snapshots. Other data stored on the storage volumes (not part of the selected data) remain available for use and retain changes made prior to the synchronization. |
