[英]Where does SQL Server restore backup from if I select Database as the source?
When I restore an SQL server database from backup, I usually do it from a .bak
file on the disk. 当我从备份还原SQL Server数据库时,通常是从磁盘上的
.bak
文件执行的。 There is also an option to restore from Database
as a source - see this picture 还有一个从
Database
还原为源的选项-参见此图
Is this backup restored from the database log file? 是否从数据库日志文件还原了此备份?
It's from existing backups from databases that have been created on the server. 它来自服务器上已创建的数据库的现有备份。 It's essentially a list of all databases that have at least one recorded backup in the
msdb
database. 本质上,这是
msdb
数据库中至少有一个记录的备份的所有数据库的列表。
Select the database to restore from the drop-down list.
从下拉列表中选择要还原的数据库。 The list contains only databases that have been backed up according to the msdb backup history.
该列表仅包含根据msdb备份历史记录备份的数据库。
