rsync est un logiciel pour copier des fichiers rapidement d’une source vers une destination (localement, ou à travers le réseau). Les copies par le réseau utilisent par défaut SSH (sous Debian GNU/Linux).

rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. Also, rdiff-backup can operate in a bandwidth efficient manner over a pipe, like rsync. Thus you can use rdiff-backup and ssh to securely back a hard drive up to a remote location, and only the differences will be transmitted. Finally, rdiff-backup is easy to use and settings have sensical defaults.

This tutorial describes how to do automated server backups with the tool rdiff-backup. rdiff-backup lets you make backups over a network using SSH so that the data transfer is encrypted. The use of SSH makes rdiff-backup very secure because noone can read the data that is being transferred. rdiff-backup makes incremental backups, thus saving bandwidth.

RIBS is an incremental backup system written in PHP which utilizes some common *nix programs (specifically rsync, ssh and cp). Incremental backups mean frequent backups can be done (i.e. hourly) with only around 2x the space of the full backup. Using rsync means that RIBS can act as both a backup script on a local machine, or as a script to backup several network hosts. It is designed to be highly configurable and highly informative to the system administrator. There is a high amount of error checking, and logging/email capabilities.
