REM Delete old backup files

FORFILES /P %dbbak_dir% /D -7 -M %B_Database_Name%*.log /C "cmd /c del @file"
REM Delete Temp files
DEL /Q %dbbak_dir%FULL_backup.sql

说明：

1. 为避免 Windows 自带 FTP Client 的 PORT、PASV问题，使用 ncftp client

2. 保留最新 7 天的备份，使用 Resource kit 里的命令 FORFILES 删除老备份文件

3. ftp 目的机器是一个 linux 系统，用下面的 shell 脚本删除老备份文件

#！/bin/sh
cd /home/dbbak/
if [[ -s mm_db_`date +%Y%m%d`*.BAK ]]
then
#echo "not 0"
find . -mtime +7 | xargs rm
