There is no SQL Database file size restriction as this SQL recovery software recovers database from any size of corrupt MDF and NDF files.

Stellar SQL Recovery does not require an SQL Server installation for displaying the preview of repairable database objects. This implies that you can verify the recovery results after performing a database scan using the software without having MS SQL Server pre-installed on your system.

The software however, needs an installation of SQL Server for saving the recovered database objects. The tool works by creating a new SQL Server database, and then saving all the recovered objects to this new database.

You should make a copy of your database and run recovery on this copy instead of the original file in order to mitigate the risks of any accidental damage to the file. The software by itself is equipped to prevent any modifications to your database. However, if something goes awry (power spike, system glitch), you may run the risk of damaging the database structure or the contents of your database file.
