Line 34: * GDPS/XRC: It is an asynchronous [[Extended Remote Copy]] (XRC) technology with no restrictions on distance. XRC copies data on storage devices between two sites such that only a few seconds of data may be lost in the event of a failure. If a failure does occur, a user must initiate the recovery process. Once initiated, the process is automatic in recovering from secondary storage devices and reconfiguring systems. * GDPS/GM: It is an asynchronous [[IBM Global Mirror]] technology with no restrictions on distance. It is designed to recovery from a total failure at one site. It will activate secondary storage devices and backup systems. * GDPS/MGM & GDPS/MzGM: These are configurations for systems with more than two systems/sites for purposes of disaster recovery. GDPS/MGM and GDPS/MzGM are based on GDPS/PPRC and GDPS/XRC, respectively.~~uuuuuuuuuuuu~~ ==See also==
