When a SQL Server database is not going to open and DBCC CHECKDB can not restore it safely, Stellar Restore for MS SQL presents a last-resort technique to scan broken MDF or NDF information, preview recoverable objects, and export chosen information. It isn’t an alternative to a examined backup, however it may be helpful when the built-in restore path dangers deleting pages or when no clear restore level is offered.
What Is Stellar Restore for MS SQL?
Stellar Restore for MS SQL is a restoration software from Stellar Information Restoration for database directors and IT groups. It reads broken Microsoft SQL Server database information and makes an attempt to reconstruct recoverable content material when native instruments can not return the database to service.
The software program scans MDF and NDF information for database objects. That may embrace tables and indexes, whereas saved procedures, triggers, and keys seem individually within the restoration view. Directors can examine the outcomes earlier than saving something, which issues when just a few business-critical tables are wanted.
Somewhat than asking a staff to rebuild a schema by hand, the appliance analyzes the broken file itself. That’s most related after a failed storage write, a corrupt file header, or a database that is still in a SUSPECT or RECOVERY_PENDING state after an abrupt reboot.
Why Would You Want Specialised SQL Restoration Software program?
SQL Server databases can turn into corrupt after I/O errors, controller faults, or interrupted writes. DBCC CHECKDB can establish consistency issues, however its most aggressive restore possibility could take away broken information pages to revive structural consistency.
Restoring a known-good backup ought to stay the primary alternative. Nonetheless, restoration strain is actual: 50% of information middle operators reported at the least one impactful outage throughout the earlier three years in Uptime Institute’s 2025 survey. When the newest backup is incomplete or a restore command would discard data, a separate restoration software may also help a staff assess what stays earlier than making an irreversible alternative.
Key Options of the Software program
- MDF and NDF restore: The core engine processes each main MDF information and secondary NDF information.
- Object-level restoration: The software program can get better particular person objects as an alternative of limiting the outcome to uncooked rows.
- Granular preview: Directors can examine tables and different objects within the interface earlier than saving recovered information.
- Deleted-record restoration: An possibility is offered to find data beforehand deleted from tables.
- Superior Scan: When a typical scan can not learn sufficient of the file construction, Superior Scan performs a deeper cross.
- Versatile export: Recovered information might be saved to a reside SQL Server occasion, a brand new database, or codecs similar to CSV, HTML, and XLS.
- Parallel processing: The appliance can use a number of processor cores. Restoration velocity will nonetheless rely closely on storage throughput and the extent of corruption.
How the Restoration Workflow Operates
The workflow follows 4 clear levels:
- Choice: Select the broken MDF or NDF file.
- Scanning: Run a typical scan first, then use Superior Scan if the primary cross can not establish the required objects.
- Preview: Evaluate recoverable content material within the tree-style interface.
- Exporting: Save verified information to a reside surroundings, a brand new database, or an exterior file format.
Repairing Databases With out SQL Server Put in
When an area SQL Server surroundings is unavailable, Stellar additionally offers an internet restore possibility for an preliminary evaluation. A person can add an MDF file by way of a browser and examine whether or not recoverable content material is current earlier than establishing native restoration infrastructure.
Stellar’s on-line SQL restore service helps MDF information as much as 500 MB as of August 2026. That makes it higher suited to a small database or a diagnostic pattern than to a big manufacturing file, particularly when the file accommodates delicate buyer, monetary, or well being information.
Tiered Editions and Backup Assist
Stellar separates its features by version. The Company version focuses on database-file restore, whereas Technician and Toolkit add choices for harder restoration circumstances.
Technician customers can course of corrupt backup information with the .BAK extension, which issues when each the lively database and its backup are broken. The Toolkit version provides transaction-log evaluation and database conversion, giving groups extra choices when they should examine exercise or transfer recovered information into one other format.
Compatibility and Pricing for Microsoft SQL Server Restoration
As of August 2026, Stellar states that the product helps databases created in SQL Server 2025, SQL Server 2022, SQL Server 2019, and earlier releases. The product is offered for Home windows and Linux environments, which may also help organizations supporting older database estates alongside newer methods.
| Version | Annual Value | Major Focus |

The free trial lets directors scan a file and preview recoverable information earlier than they purchase. The trial can not show that each document might be restored, however it may possibly present whether or not the precise tables and objects your staff wants are seen earlier than you decide to a license.
For a badly broken SQL database, specialised restore software program generally is a wise ultimate possibility after backup restoration has been dominated out. Information restoration from a verified backup stays safer as a result of it preserves a known-good state, however Stellar Restore for MS SQL may also help get better chosen elements when that path is unavailable.
Select the version primarily based on the failure you truly face: an MDF or NDF downside could solely want Company, whereas a corrupt .BAK file factors to Technician and log evaluation factors to Toolkit. Run the trial in opposition to a replica of the broken file, doc the objects it finds, and maintain production-sensitive information out of third-party providers until your safety coverage permits that switch. Your subsequent precedence must be testing restores in SQL Server Administration Studio, as a result of a restoration software is most precious when it’s the exception, not the restoration plan.
