Remote Copy and volume replication

Remote Copy is an asynchronous replication of data. Network RAID is a synchronous replication of
data. Using synchronous Network RAID on multiple storage systems within a cluster in combination
with asynchronous Remote Copy on a different cluster of storage systems creates a robust,
high-availability configuration.

How it works
Remote Copy stores remote snapshots on a machine in a geographically
separate location. The remote snapshots remain available in the event of
a site or system failure at the primary site.
Remote Copy eliminates the backup window on an application server by
creating remote snapshots on a backup server, either local or remote,
and back up from that server.
Remote Copy makes a complete copy of one or more volumes without
interrupting access to the original volumes. You can move the copy of
the volume to the location where it is needed.
Remote Copy creates copies of the original volume for use by other
application servers.
