推荐答案

DECLARE @name VARCHAR(50) -- database name  
DECLARE @path VARCHAR(256) -- path for backup files  
DECLARE @fileName VARCHAR(256) -- filename for backup  
DECLARE @fileDate VARCHAR(20) -- used for file name


-- specify database backup directory
SET @path = 'C:\Backup\'


-- specify filename format
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')  -- exclude these databases


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

2.在sql代理中按照规定的时间安排此过程。

或在任务计划程序中安排它如果您使用的是Express Edition
