Others have already mentioned 'hardware-based' facilities like PPRC & XRC. One aspect of those options that is sometimes overlooked is they are chargeable features on the source ( for both facilities ) and target ( for PPRC only ). The XRC option also would require some 'configuration' considerations related to whether the data would be 'pushed' or 'pulled' from the primary site. The distance between the sites and your 'network conntection options' may also limit your options.
Also, others have already mentioned using the TDMF product. One option that TDMF offers is to use TCP/IP to 'move' the data vs. ESCON/FICON channels. I have used that option to 'move' more than 12TB ( about 2100 volumes ) of data a fairly large distance ( Midwest USA to UK ). That option took some tweaking, within TDMF V4 and the z/OS TCP/IP stack ( we were at z/OS R7 ) but in the end, the 'move' was performed relatively easily, with fairly low pain.
