Microsoft SQL Server has a widely used database management system for storing and retrieving data. It stores its files in MDF, NDF, and LDF format. If a SQL database is lost due to disasters, then backups act as a silver lining. That is why MS SQL administrators always suggest making backups regularly. But data loss can occur at any time due to multiple known and unknown causes. Under such circumstances, if a user has MDF and LDF files as the backup, then it is easy to restore the deleted and lost database back to its original state. Otherwise, repairing corrupt SQL files, tables, and other components can be a tedious task if users do not follow the right technique. There are manual commands available that shows how to recover SQL Server database without backup, but an authentic third-party software is always the best approach to do it.
