A. INVENTION
The invention at issue on appeal replicates data in a computer
network. Accelerated business practices and the globalization of the
marketplace require business communications and operations to function
around-the-clock. Corporate data repositories must be able to provide
critical data regardless of interruptions caused by hardware failure, software
failure, or geographical disaster. To achieve the necessary data continuity
and resilience, businesses employ remote data repositories to back-up and
store the critical data (Specification 1.)
For its part, the Appellants' invention replicates data from a local
location and forwards the replicated data to a remote location. (Id. 6.) The
invention uses the Transmission Control Protocol/Internet Protocol, i.e.,
TCP/IP, to forward the replicated data. (Id. 7.)
Claim 21 which further illustrates the invention, follows.
21. In a storage network, a method to create a replica of
selected data in said storage network, said method comprising
the steps of:
instructing a first data replication facility at a first
electronic device in said storage network to track changes to
one or more storage locations of a first storage medium that
correspond to said selected data;
instructing said first data replication facility to generate
said replica of said selected data based on said tracked changes
to said one or more locations of said first storage medium;
placing said replica of said selected data in a data
structure; and
