我主要用它来备份数据库, 没时间做大修改, 如果感兴趣你可以修改下, 推荐哈

# 本参数如设置为1，则打包压缩/www/users/目录时候，
# 将会把每个站点单独生成一个对应的tgz压缩文件
# 本参数如果为0，则/www/users/下所有站点将打包成为一个users.tar.gz的大文件
# 为了便于下载备份和解压缩备份文件，本参数默认设置为1

# 本参数如设置为1，则打包压缩/var/lib/mysql/目录时候，

# 保留多少份旧的备份？
# 即除了当前最新的这个备份之外，还保留几个备份，最少为0个，默认为1
# 如果设为0，则只保留一个备份，每次备份的时候都会把以前的备份删除
