摘要

Provided are a computer program product, system, and method for creating a restore copy from a copy of source data in a repository having source data at different point-in-times and reading data from the repository for the restore copy. The source data is copied as of an initial point-in-time to a repository. Point-in-time copies at different point-in-times of the source data are initiated following the initial point-in-time. Change information for the point-in-time copy indicating changed data in the source data that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time are transmitted to the repository. For each point-in-time copy, changed source data indicated in the change information for the point-in-time copy as changed is copied to the repository. A restore copy is returned to a restore request before the source data in the repository as of a restore point-in-time is copied to the restore copy.
