Systems and methods for minimizing network bandwidth for replication/back up

摘要

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.

主权项

1. A method for backing up a client data set on a computer, comprising:
identifying changed files; and 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, or rearrangements of data in the file; transmitting one more changed segment(s) in the file; writing a manifest file reflecting the new target state as an incremental backup; expanding one or more patch sets and saving the patch sets with a file system to provide an incremental backup while generating a full backup; taking a snapshot after a full backup providing for a version history; and providing a mountable file system for user access to full backups with version history data located on the server.
