SYSTEMS AND METHODS FOR MINIMIZING NETWORK BANDWIDTH FOR REPLICATION/BACK UP
First Claim
20-1. The system of claim 21, wherein the client software communicates using Web-based Distributed Authoring and Versioning to collaborative updating and management of files on remote web servers and wherein the client software selects the number of threads, and wherein the client software comprises a configurable parallelism selection for multi-processor efficiency and high latency connections, or for backing up NAS/SAN or RAID arrays with multiple disks.

Abstract
Systems and methods are disclosed for backing up a client data set on a computer by identifying changed files; generating a first sub-file signature for one or more segments of a changed file; subsequently generating a second sub-file signature for each file segment to detect insertions, removals, and rearrangements of data in the file; transmitting one more changed segment(s) in the file; and writing a manifest file reflecting the new target state.

21-2. The system of claim 21, wherein the data storage silos comprises a pair of head nodes and a plurality of storage nodes, wherein each storage node comprises a computer with disks and an on-disk encryptor to generate clear text and sent over an Internet Small Computer System Interface (iSCSI), wherein iSCSI traffic is load balanced and fails over network links and connected to a plurality of switches and wherein iSCSI data comprise whole disk mappings and wherein the head nodes create RAID stripes across the storage nodes.
