 命令（可同时备份多个数据库）：

DECLARE
 @FileName VARCHAR(200),
 @CurrentTime VARCHAR(50)

SET @CurrentTime = CONVERT(CHAR(8),GETDATE(),112) + CAST(DATEPART(hh, GETDATE()) AS VARCHAR) + CAST(DATEPART(mi, GETDATE()) AS VARCHAR)

SET @FileName = 'D:\CE_BPS\DataBaseBackup\DPC_TEXT' + @CurrentTime
BACKUP DATABASE [CE_BPS_DPC_TEXT] TO DISK = @FileName WITH NOINIT, NOUNLOAD, NAME = N'CE_BPS_DPC_TEXT-备份', NOSKIP, STATS = 10, NOFORMAT

SET @FileName = 'D:\CE_BPS\DataBaseBackup\DPC_IMAGE' + @CurrentTime
BACKUP DATABASE [CE_BPS_DPC_IMAGE] TO DISK = @FileName WITH NOINIT, NOUNLOAD, NAME = N'CE_BPS_DPC_IMAGE-备份', NOSKIP, STATS = 10,NOFORMAT

备份所有用户数据库
