sqlserver 2005 定时任务计划 批量文件备份脚本

在网上找一了一个多数据库同时备份的脚本，之前存在少许问题作了更改，脚本如下：

@echo off
set svr=sqldb
set svrrole=bozch
set nowtime=%date:~0,10% %time%
set year=%date:~0,4%
set month=%date:~5,2%
set day=%date:~8,2%
set today=%year%-%month%-%day%
if "%time:~0,1%" == " " (set nowh=%time:~1,1%) else (set nowh=%time:~0,2%)
　　set rar="c:\Program Files\WinRAR\Rar.exe"
　　set rarlist="D:\backupdb\script\rarlst.txt"
　　set ftplist="D:\backupdb\script\ftplst.txt"
　　set baklog=D:\backupdb\script\tkblbackup.log
@echo. >> %baklog%
@echo -------------------------------------------------- >> %baklog%
@echo %nowtime% BackupScript is starting....... >> %baklog%

::数据库备份语句，可添加多个数据库
　　for %%a in (test) do (
　　@echo %nowtime% BackupDB %%a is beginning....... >> %baklog%
　　@osql -s localhost -U sa -P sa -Q "backup database %%a to disk='D:\backupdb\backupdb\%%a_%svr%_%today%.bak' with init" >> %baklog%
　　echo D:\backupdb\backupdb\%%a_%svr%_%today%.bak >> %rarlist%
　　)
::Rar files
　　%rar% a D:\backupdb\backupdb\%svrrole%_%svr%_%today%.bak.rar @%rarlist%  >> %baklog%
　　cd /d D:\backupdb\backupdb
　　del *.bak

echo. > %rarlist%
@echo -------------------------------------------------- >> %baklog%
@echo. >> %baklog%
