A computer program product, system, and method for creating a restore copy (124) from a copy of source data (104) in a repository (110) having source data (104) at different point-in- times. All the source data (104) as of an initial point-in-time is copied to a repository (110). In response to completing point-in-time copies following the initial point-in-time, change information is transmitted to the repository (110) indicating changed data (120) in the source data (104) that changed between the point-in-time of the point-in-time copy and a subsequent point-in-time. For each point-in-time copy, copying changed source data comprising source data (104) indicated in the change information for the point-in-time copy as changed to the repository (110). A restore request is received to restore the source data (104) as of a restore point-in-time. The source data (104) in the repository (110) as of the restore point-in-time is copied from the repository (110) to a restore copy (124). |
