linux下自动备份脚本并上传到ftp服务器

#!/bin/bash

#设置日志文件，前提建好了/backup/log目录

LogFile=/backup/log/`date +"%Y-%m"`.log

#备份源目录

SourceDir=/cvs

#备份目标

BakDir=/backup

#保存20天过期自动删除

RetainDay=20

#备份的内容可以写进project.lst，如cvs目录下有a,b,c三个目录，project.lst填写多少就备份多少，下面是备份的

#具体脚本，其核心是tar打包，并把重要的内容记录到日志文件里

ProjectLst=/backup/project.lst
