Patent ID: 7734884

Claim:
A storage system, comprising: a data center; a local destination coupled to the data center; and a remote destination coupled to the data center and to the local destination, wherein the storage system provides storage configurations for a data center by providing synchronous data transfer from the data center to a local destination, establishing a first connection between the data center and a remote destination to provide chunks of data from the data center to a remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks, establishing a second connection between the local destination and the remote destination to provide chunks of data from the local destination to the remote destination, wherein each chunk of data represents data written after a first time and before a second time and wherein the second time for one of the particular chunks corresponds to a first time for a subsequent one of the particular chunks, and enabling at least one of the first and second connections to transfer chunks of data to the remote destination.
