摘要: Methods, computing environments, and computer program products are provided for replicating data. Point-in-time copy parameters are generated at a primary host site. A side file entry having the point-in-time copy parameters and a track information field (TIF) associated with the point-in-time copy parameters is generated. The side file entry is transferred to a secondary host site. A point-in-time copy process is performed at the secondary host site based on the point-in-time copy parameters and the TIF.
