Rsync

rsync is a replacement for rcp that has many more features. rsync uses the "rsync algorithm" which provides a very fast method for bringing remote files into sync by sending just the differences in the files across the link, without requiring that both sets of files are present at one of the ends of the link beforehand.

At first glance this may seem impossible because the calculation of diffs between two files normally requires local access to both files. A technical report describing the rsync algorithm is included with this package.

Features include:

  • Ability to whole directory trees and filesystems
  • Optionally preserves symbolic links, hard links, file ownership,
    • permissions, devices and times
  • Requires no special privilages to install
  • Internal pipelining reduces latency for multiple files
  • Can use rsh, ssh or direct sockets as the transport
  • Supports anonymous rsync which is ideal for mirroring
