你想怎么做？
看下联机帮助
把那些命令写在SQL语句再调用就行啦

BACKUP
备份整个数据库、事务日志，或者备份一个或多个文件或文件组。有关数据库备份和恢复操作的更多信息，请参见备份和还原数据库。

语法
备份整个数据库：

BACKUP DATABASE { database_name | @database_name_var }
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text' | @text_variable } ]
[ [ , ] DIFFERENTIAL ]
[ [ , ] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text' | @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]
