The disk structure version of The backed up database is 611, and the server supports version 539. The database cannot be restored or upgraded.

We all know that the database files of the advanced version cannot be restored or appended to the lower version, because the format of the files of the higher version and the lower version is different. If you try to append or restore a database of a lower version to a database of a lower version, you will see an error similar to the following:

 

The disk structure version of The backed up database is 611, and the server supports version 539. The database cannot be restored or upgraded. Restore
The filelist operation ends abnormally. (Microsoftsql server, error: 3169)

 

We can see that there are two version numbers, not the server version number (select @ version) we usually see, but the internal database version number of sqlserver. These versions do not have official documentation. However, you can use the databasepropertyex 'version' option to obtain the version number.

 

Select databasepropertyex ('master', 'version ')

 

Here, I found the configuration table of the internal database version corresponding to all sqlserver versions on the Internet (Ternal SQL Server database version numbers):

 

Target SQL Server version	Source SQL Server version	Internal database version
SQL Server 2008 r2	SQL Server 2008 r2	665
	SQL Server 2008	661
	Sqlserver 2005 with vardecimal Enabled	612
	SQL Server 2005	611
	SQL Server 2000	539
SQL Server 2008	SQL Server 2008	661
	Sqlserver 2005 with vardecimal Enabled	612
	SQL Server 2005	611
	SQL Server 2000	539
SQL Server 2005 sp2 +	Sqlserver 2005 with vardecimal Enabled	612
	SQL Server 2005	611
	SQL Server 2000	539
	SQL Server 7	515
SQL Server 2005	SQL Server 2005	611
	SQL Server 2000	539
	SQL Server 7	515
SQL Server 2000	SQL Server 2000	539
	SQL Server 7	515
SQL Server 7	SQL Server 7	515

 

In this configuration table, we can see that the cause of the error is to try to restore the 2005 backup file to 2000. If you do not have version 2005, you can only export the 2005 database script to version 2000 and then import the data.

 

Description of the databasepropertyex 'version' option on msdn: the internal version number of the SQL server code used to create a database. The SQL Server tool is only used internally for upgrade.
