how to backup and restore database of SQL Server

Back up

1,右键选中需要备份的数据库，Tasks-->Backup

2.General中，Destination，先remove掉之前的，然后再Add

需要注意的是，add的文件，必须要以.bak为后缀名，否则后面restore的话，不会显示出备份的文件

Restore

1.在数据库服务器的Databases上右键，选择Restore Database

1.1  General选项卡

1.1.1选择Device进行浏览，找到之前备份的文件。在查看文件的时候，默认是查看.bak文件。

不过也可以选择all files，那样可以看到所有的文件

1.1.2  General里面，Destination中的Database需要起一个不同的名字，这个名字是显示在ManagementStudio中的

选择路径之后，点击刷新的图标，然后下方会自动筛选

可以同时添加多个备份数据库，但是每一个数据库的restore plan是需要切换选项卡来进行独立设置的

1.2  Files选项卡

在General中，每切换一个数据库，Files选项卡中都需要独立配置一下

Logical File中的Rows Data和Log，都需要进行重命名，确保不重名。Restored as 这个列的里面的数据需要重命名

1.3  Options选项卡

取消勾选Tail-log backup

The error message you are getting tells you exactly what you need to do if you don't care about the existing database or log.

RESTORE DATABASE DAtabaseName FROM DISK = 'C:\DBName-Full Database Backup'
WITH REPLACE

In SQL Server Management Studio (Tasks > Restore), you can add the WITH REPLACE option by opening the page "Options" on the left side and ticking "Overwrite the existing database".
