Rsync is one of the best backup software tool. It was originally designed to replace rcp, the venerable old Unix remote copy program. Because of its sophisticated means of synchronizing and transferring files and directories, rsync is widely used for mirroring Web sites. rsync transfers only the changes in files, using the devilishly clever rsync algorithm. It calculates difference without needing both files to be present.
Rsync greatly improves efficiency when compared to traditional remote backup methods. By synchronizing only those files that have changed since the last backup, using rsync results in large bandwidth savings.
When combined with on-the-fly compression, performing daily rsync backup can result in less data transfer than it would take to perform two backups using the .tar.gz method in a given month / week / day. Rsync is effectively deployed on load balanced corporate servers and it plays major role in synchronizing data amongst all the database and http servers. Many leading corporate websites use rsync to ensure 100% data transfer between 2 or more servers.
