在SQL SERVER中，添加JOB，可以使用以下语句设置定期备份数据库。
DECLARE @name VARCHAR(50)--databasename
DECLARE @path VARCHAR(256)--pathforbackupfiles
DECLARE @fileName VARCHAR(256)--filenameforbackup
DECLARE @fileDate VARCHAR(20)--usedforfilename SET @path='E:\Backup' SELECT @fileDate=CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR SELECT [name] FROM master.dbo.sysdatabases WHERE [name] NOT IN('master','model','msdb','tempdb')
OPEN db_cursor FETCH NEXT FROM db_cursor INTO @name WHILE @@FETCH_STATUS=0
BEGIN
SET @fileName=@path+@name+'_'+@fileDate+'.BAK'
BACKUP DATABASE @name TO DISK=@fileName
FETCH NEXT FROM db_cursor INTO @name
END CLOSE db_cursor
DEALLOCATE db_cursor
