Summary: The blog describes the manual and software methods to recover SQL Server Database without backup. You can manually repair the database by running the ‘DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS’ command with some data loss. For quick and risk-free database recovery, consider using a specialized SQL database recovery software, such as Stellar Repair for MS SQL.
Data loss can occur anytime due to several known and unknown reasons. Many tables and other components of the database can turn unreadable without any prior notification or alerts. And a recent, good known backup copy of the SQL Server Database can help restore the deleted and lost database back to its original state. That is why administrators always recommend backing up databases regularly.
If you do not have an updated backup or if the backup is corrupt, it can be difficult to recover SQL Server database and its deleted or inaccessible data.
Note: This method will only work if the database you want to restore is still attached to the SQL Server instance. If your database is offline, you cannot execute the DBCC CHECKDB command. In that case, the only option is to use a specialized SQL recovery tool.
If you do not have backup of your SQL database, you can try repairing it by running the ‘DBCC CHECKDB REPAIR_ALLOW_DATA_LOSS’ command.
|Caution! Running DBCC CHECKDB does not guarantee bringing the databases to a consistent state. Also, using the ‘REPAIR_ALLOW_DATA_LOSS’ option can result in data loss.|
Note: If DBCC CHECKDB reports any errors, it will recommend minimal repair options to fix the errors.

Unlike the ‘DBCC CHECKDB’ repair command, Stellar Repair for MS SQL software does not involve data loss risk. The software is purpose-built to help users repair corrupt SQL database (MDF and NDF) files without backup, preserving the original file data. Once repaired, the file can be used to restore the database to its original, intact form.
The SQL database recovery tool can also handle all types of database corruption errors, such as database consistency errors, database in suspect mode, recovery pending mode, etc.
The software can help recover unreadable database objects from corrupt SQL database MDF and NDF files.
|Points to Consider Before Using the Software: |
1. Back up the SQL Server database you want to repair to prevent further damage. Also, ensure that the repair process is executed on the backup file and not the original database file.
2. Application auto-checks the SQL Server version: however, if the file is severely corrupted, you can select the SQL Server edition manually under the “Select Database Versions” section. If the selected version of the Server database file is invalid, the tool will display an “Invalid database version, Select the appropriate database version” message.
Step 1: Download, install and run Stellar Repair for MS SQL software.
Step 2: In the software main interface window, click Browse to select the database file you want to recover.
Note: If you do not know your db file’s location, click ‘Search’ to find and select the file.
