rsync-linux备份脚本,rsync-linux脚本其实只有一条命令：r

编写为脚本

这个脚本的基本形式来自于 rsync 的网站。其实只有一条命令：

rsync –force –ignore-errors –delete –delete-excluded –exclude-from=exclude_file –backup –backup-dir=`date +%Y-%m-%d` -av

关键的参数是：

–backup: 在覆盖前备份文件

–backup-dir=`date +%Y-%m-%d`: 为备份的文件建立一个备份目录，看上去就像: 2002-08-15

-av: 存档(archive)模式和详细输出(verbose)模式。
