svn每日备份和删除（上传到云）

svn 定时备份的脚本，要求备份完成后发送邮件，把备份的大小、压缩的大小，过滤的目录都罗列

通过远程服务器的nfs服务 把备份盘挂载到本地。

#!/bin/sh
# 两者只能选填一个，都为空就全备份，格式 ('deploy_doc' 'weibo')
#过滤目录 ，指定不备份
FILTER_DIR_ARR=()
#包含目录， 只备份列出的文件
ALLOW_DIR_ARR=('deploy_doc' 'weibo')

#本地保留天
LOCAL_STAY_DAYS=6
#远端保留天
REMOTE_STAY_DAYS=15

# 发送邮件
EMAIL='/usr/local/bin/sendEmail'
SMTP_SERVER='smtp.huored.com'    # SMTP服务器，变量值需要自行修改
USERNAME='sentinel@huored.com'     # 用户名，变量值需要自行修改
PASSWORD='8issHFw4s'             # 密码，变量值需要自行修改

执行：

       将过滤目录和包含目录直接写到脚本，后期可以用配置文件。
