Shift is high-performance local and remote file transfer framework. It can recover from varying networking and storage errors. Shift uses cryphtographic hashes to verify transfer integrities, throttles network connections if need be, instruments load balancing over different connections, but als parallelizes redundant connections. It specifically works with large amounts of data, and applies the same recovery facilities to local filesystem transfers.
