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.
