SQL Server 自动备份脚本

以下脚本执行 SQL Server 中某一数据库全备份，并将备份文件传至另一机器。备份文件命名规则：数据库名_时间戳.BAK。

执行环境： windows 2003 server SQL Server 2000

@ECHO off

REM Backup Database Script Log Files
SET dbbak_dir=e:testdbbak

SET DBUser=sa

ECHO BACKUP DATABASE

REM FTP info
set FTP_User=user1
set FTP_PW=passwd
set FTP_IP=10.1.9.1
set FTP_PORT=21
set FTP_DIR=/home/dbbak

SET NCFTP_PATH=D:Program FilesNcFTP
"%NCFTP_PATH%ncftpput.exe" -u %FTP_User% -p %FTP_PW% -P %FTP_PORT% %FTP_IP% %FTP_DIR% %dbbak_dir%%B_Database_Name%_%B_DATE%_FULL.*

REM Delete old backup files
FORFILES /P %dbbak_dir% /D -7 -M %B_Database_Name%*.bak /C "cmd /c del @file"
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
