Network redirector systems and methods for performing data replication

A system for selecting application data to be copied in a computer network, the system comprising:

• at least one computer application configured to generate operations associated with data on a first storage device;
• a filter module disposed between the at least one computer application and the first storage device, the filter module configured to identify from the operations a plurality of data modification operations;
• a buffer;
• and
• a network redirector component in communication with the filter module and configured to temporarily store a copy of the data modification operations in the buffer while allowing the data modification operations to pass through to the first storage device, the network redirector component being further configured to transmit the copies of the plurality of data modification operations to a destination system, to be copied to a second storage device, without first writing the copies of the plurality of data modification operations to the first storage device.

A system for acquiring data for replication on a network storage device, the system comprising:

• means for generating operations associated with data on a first storage device;
• means for identifying from the operations a plurality of data modification operations, said means for identifying being disposed between said means for generating and the first storage device;
• and
• means for temporarily storing a copy of the data modification operations while allowing the data modification operations to pass through to the first storage device, said means for storing being further configured to transmit the copies of the plurality of data modification operations to a destination system, to be replicated to a second storage device, without writing the copies of the plurality of data modification operations to the first storage device.
