@echo off  
rem --------------------- 配置: ftp上传参数,及本地文件目录(数据库备份的临时目录)-----------------  
set "PUT\_FTP\_SERVER=192.168.1.100"  
set "PUT\_FTP\_PORT=21"  
set "PUT\_FTP\_USERNAME=ftpuser"  
set "PUT\_FTP\_PASSWORD=ftppasswd"  
set "PUT\_DIR=/"  
set "LOCAL\_DIR=D:/sql\_dbbackup/"

rem ----------------------程序开始-----------------------------------------------------------------------  
echo begin\_backup\_db  
rem 调用数据库备份存储过程,参数为本地目录. 数据库返回"过期需要删除的备份文件"  
sqlcmd -E -S 127.0.0.1,1333 -d master -v BAK\_PATH="'%LOCAL\_DIR%'" -Q "execute dbo.p\_job\_backup $(BAK\_PATH);" -t 4800 -h -1 -W | findstr bak>>del\_file.txt

rem 开始自动上传(上传完删除对应的本地文件)  
echo begin\_ftp\_upload  
call :uploaddir "%LOCAL\_DIR%" "%PUT\_DIR%"

rem 检查是否上传失败,失败则记录数据库日志  
echo begin\_check  
for /f "delims=" %%i in ('dir /b /a-d "%LOCAL\_DIR%\*.bak"') do echo %%~nxi>>local\_file.txt  
if not exist local\_file.txt goto :delete\_remote  
for /f "delims=" %%i in (local\_file.txt) do (  
sqlcmd -E -S 127.0.0.1,1333 -d master -v FILE\_NAME="'%%i'" -Q "insert into t\_log\_backup(loglevel, filename, remark) values(1,$(FILE\_NAME),'严重错误:上传备份文件失败,请检查ftp权限.同时它会导致本地磁盘满.');" -t 3600  
)  
del /f/q local\_file.txt

rem 开始删除远程过期文件  
echo begin\_del\_remote  
:delete\_remote  
call :delremotefile "%LOCAL\_DIR%" "%PUT\_DIR%"

rem 启动数据库发送邮件(即发送错误日志)  
sqlcmd -E -S 127.0.0.1,1333 -d master -Q "execute dbo.p\_sendmail;" -t 120  
echo end.
