SQL Server is a widely used relational database management system (RDBMS). Microsoft produces it, and it runs on the Windows operating system. SQL Server stores data in tables and uses Structured Query Language (SQL) for data access.
Due to its popularity, SQL Server is a target for hackers and malicious software. Hardware failures and user errors can also cause data loss in SQL Server databases.
How to fix SQL Server data loss and restore damaged database structures and lost data
Before You Begin
- Make sure you have a backup of your SQL Server database. Without a backup, you cannot recover your lost data.
- Try to reproduce the error or take a snapshot of the database before you start the recovery process. This will help you determine the cause of the data loss and prevent it from happening again.
- Download and install Stellar SQL Server data recovery software on your computer.
- Connect to your SQL Server database using SQL Server Management Studio (SSMS).
Recovering Lost Data
- In SSMS, right-click on the database you want to recover and select “Restore Database”.
- Select “From device” and click the “…” button in the Restore Database dialogue box.
- In the Specify Backup dialogue box, select the backup file you want to use for the recovery and click “OK”.
- In the Restore Database dialog box, select the “Timeline” tab.
- Select the point in time when you want to restore your database and click on “OK”.
- In the Confirm Restore Sequence dialogue box, click on “Yes”.
- In the Restore Successful dialogue box, click on “OK”.
Your lost data should now be recovered.
Restoring Damaged Database Structures
- In SSMS, right-click on the database that you want to recover and select “Tasks” > “Restore” > “Database”.
- Select “From device” and click the “…” button in the Restore Database dialogue box.
- In the Specify Backup dialog box, select the backup file you want to use for the recovery and click “OK”.
- In the Restore Database dialog box, select the “Options” tab.
- Select the “Overwrite the existing database” option and click “OK”.
- In the Confirm Restore Sequence dialog box, click on “Yes”.
- In the Restore Successful dialog box, click on “OK”.
Your damaged database should now be recovered.
Preventing Data Loss
- Make sure you have a valid backup of your SQL Server database.
- Test your backups regularly to ensure that they are working correctly.
- Use a reliable backup software solution that supports incremental and differential backups.
- Store your backups safely (e.g., off-site storage) to protect them from disasters (e.g., fires, floods, etc.).
- Implement security measures to protect your SQL Server database from hackers and malicious software.
- Train your users on using the SQL Server database safely and prevent them from making mistakes that can cause data loss.
- Monitor your SQL Server database regularly to identify and fix potential problems before they cause data loss.
- Use a reliable SQL Server monitoring tool to monitor your database and send alerts when potential issues are detected.
