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.

Rsyncbackup.sh

cat rsyncbackup.sh  
#!/bin/bash
# Backup Script (RSYNC)
# ---> différence RDIFF-BACKUP/RSYNC: syntaxe "exclude", avec le "=" et le retrait du basename

# V 1.0
# from rdbackup.sh 2.3 (RDIFF-BACKUP)

if [ $# -gt 0 ]

   . $1
else
# Application specific
