Rsync script

Rsync est disponible sur la plupart des systèmes. Le script ci-dessous tiré du script Rdiff-backup est utile quand ce dernier ne peut pas être utilisé.

TODO : ajouter une sauvegarde des fichiers supprimés par --delete (--backup --backup-dir, voir http://www.demongeot.biz/tutos/Rsync.html)
