1.通过sql server 维护计划备份数据库,每个库独立建立文件夹
2.通过下面vbs脚本将文件复制到磁带可以备份的共享位置(权限可控),windows schedule定时执行;文件很大时,可直接磁带备本机或直接复制到对应位置.
1 @echo off 2 @REM 删除旧的备份 3 @del \\server_name\sql_bck$\*.bak 4 5 @Rem 取当天备份文件名 6 set "bakname=*%date:~0,4%_%date:~5,2%_%date:~8,2%*.bak" 7 @Rem 复制当天的备份 8 9 copy D:\SQLDataBackup\folder1\%bakname% \\server_name\sql_bck$\ >>d:\backupforsql.log 10 11 copy D:\SQLDataBackup\folder2\%bakname% \\server_name\sql_bck$\ >>d:\backupforsql.log 12 13 copy D:\SQLDataBackup\folder3\%bakname% \\server_name\sql_bck$\ >>d:\backupforsql.log 14 15 echo 16 date /t >>d:\backupforsql.log 17 time /t >>d:\backupforsql.log 18 echo Backup END >>d:\backupforsql.log 19 echo ######################################################### >>d:\backupforsql.log 20 21 @Rem pause
3.sql job或windows schedule定期删除过期的备份文件
1 DECLARE @OLDDATE DATETIME 2 SELECT @OLDDATE=dateadd(day,-60,GETDATE()) 3 4 EXECUTE master.dbo.xp_delete_file 0,N'D:\SQLDataBackup\A',N'bak',@olddate,1-- 5 6 EXECUTE master.dbo.xp_delete_file 0,N'D:\SQLDataBackup\B',N'bak',@olddate,1--\%bakname% \\server_name\bck_sql$\ >>d:\backupforsql.log 7 8 EXECUTE master.dbo.xp_delete_file 0,N'D:\SQLDataBackup\CY',N'bak',@olddate,1--\%bakname% \\server_name\bck_sql$\ >>d:\backupforsql.log
