REMOTE BACKUP OF LARGE FILES

摘要

A method of backing up large volumes of data that includes identifying a data file for remote backup; transmitting two or more chunks of the data file in parallel through a communications network to a server to be stored by the server; streaming, compressing, and encrypting prior to transmission each chunk without generating additional data copies for each of the streaming, compressing, and encrypting; detecting an interruption in the transmission a chunk(s); checking the availability and reliability of the communications network; and restarting transmission of the interrupted chunk after a randomized pause period.

1. A computer-implemented method comprising:
identifying a data file for remote backup; transmitting in parallel two or more chunks of a plurality of data file chunks through a communications network to a server to be stored by the server, the chunks being streamed, compressed, and encrypted prior to transmission without generating additional data copies for each of the streaming, compressing, and encrypting; detecting an interruption in the transmission of one or more chunks; checking an availability and reliability of the communications network; and restarting transmission of the interrupted chunk after a randomized pause period.
