Every SQL Administrator at some point has experienced an error on their SQL Database, which states that 'SQL server database is not accessible after restore.' Multiple reasons can lead to this error. Here we're going to go through the top 4 reasons for this error and how you can resolve this issue.
1. Restoring the Database through backup with No-Recovery Mode
When a SQL Administrator tries to restore a database through the backup, there are multiple options available for recovery, for example, 'Recovery State with No Recovery.' In this case, backup recovery is possible, but the database is not accessible by users during the backup recovery. The script converts recovery mode to no recovery.
The next situations could be presented in your recovery process: users require the database to access it for information during the time of its backup; the SQL database is humongous, and the SQL Admins cannot select the option of 'Recovery state with no recovery,' or the backup is not in good condition. In those cases, the backup recovery for the SQL database is interrupted, and the SQL server is not accessible. The solution to this problem is to Restart the services after restore following the next steps:
- Start SQL Server Configuration Manager
- Click on the Yes button when the User Account Control dialog box appears.
- Press right-click on SQL server and click on the Restart button in the Results pane
- Click Ok, and the SQL Server Configuration Manager should close
2. Trying to restore SQL database in Recovery mode
Restarting the services may or may not restore the database. If the steps above fail, then the next best way to restore it is by restoring the database through "backup with Recovery Mode."
The SQL Administrator drafts a Script which states 'Restore Database with Recovery.' Next, Refresh the SQL server, and the database should be accessible. However, it will be rendered inaccessible in case the script is interrupted during its execution. For example, if a user tries accessing the database when the script is still running.
3. Authenticate the default DB as Master to a different User account
Sometimes, creating the databaseSQL Authentication mode login database may not let us access the data and the database, and it may not be accessible even after SQL Restore. In that case, the only way to access the database is through Windows authentication mode login. However, accessing through Windows authentication may not be a feasible option for you as it reduces the security layers in the database. Let's look at an example of why this is the case:
The name of "ABC sets the SQL Administrator." However, the user account deletes the existing user account and rebuilds with the new name. "ABC1" and assigns all SQL permissions. This change doesn't let the user access the old databases and leaves a message, "The database DB01 is not accessible (Object Explorer). Even after creating the new login in SQL server for "ABC1" and assigning the permissions as 'Master,' the problem stands unresolved with the database not accessible. In this situation, there is no way to detach the earlier database or expand the database. On analyzing the issue, it was interpreted that the problem was with Operating system login credentials where Login credentials should match with SQL server login.
4. Deploy a reliable SQL Database Recovery Software
If the SQL Server Database is not accessible after restoration, even after setting the same Login Credentials for Windows OS and SQL, search for appropriate software to repair it. One example of this is Stellar Phoenix SQL Database Repair; it is one of the best software for fixing issues and ensures that the SQL database is accessible after restore. This software helps in accessing the database on a server and also prevents further corruption.
SQL Server database is crucial for any organization. If the database is not accessible after restoration, try Stellar software, which repairs the SQL server database and ensures accessibility of it after a complete restore. Besides restoring accessibility, the software also performs recovery of deleted records and saves the recovered SQL database in any of these four options - MSSQL, CSV, HTML, and XLS format.
