Abstract:
1. A method for performing automated data replication from a first site to a second site comprising: performing a consistent split data operation splitting a synchronized copy of data from a first device in said first site, said synchronized copy being a consistent point in time copy of data from said first device, wherein performing said consistent split data operation and obtaining said synchronized copy includes suspending write operations from a host computer to a primary device of a primary site for a predetermined time period; replicating said synchronized copy of data to a second device included in said second site; and performing incremental synchronization of said second device to a third device included in said second site, wherein commands are issued from said host computer to control said automated data replication, wherein a multi-hop configuration includes said first site as a middle site, said second site as a target site, and the multi-hop configuration further includes said primary site, said first device including a mirrored copy of data of said primary device of said primary site maintained in said middle site.
