恢复完整数据备份的几个注意点

创建备份设备

use master

go

exec sp_addumpdevice ‘disk‘,‘data123‘,‘d:\123.bak‘

备份数据

backup database data1 to disk=‘d:\123.bak‘

备份日志

backup log data1 to disk=‘d:\123.bak‘

查看备份情况

restore headeronly from disk=‘d:\123.bak‘

还原完整数据及日志

restore database data1 from disk=‘d:\123.bak‘ with file=1,replace,norecovery

restore log data1 from disk=‘d:\123.bak‘ with file=2,replace,norecovery

restore log data1 from disk=‘d:\123.bak‘ with file=3,replace,orecovery

覆盖备份（init意为初始化不加参数为追加备份）

backup database data1 to disk=‘d:\123.bak‘ with init

按时间点还原完整数据及日志

restore database data1 from disk=‘d:\123.bak‘ with file=1,replace,norecovery

restore log data1 from disk=‘d:\123.bak‘ with file=2,recovery,stopat=‘2015-03-10 20:30:35.100‘
