What Are BAK & MDF File Formats?
To get started, we can explain that BAK or .bak files are the backup files of an SQL Server database. This file format contains all the database information till a specific time when the backup was taken. It is helpful for users in critical conditions like database crash, file corruption, etc for restoration process.
Now, if we talk about the master database file, it’s even more crucial. The .mdf file is the master database file which holds all the information of a database including the structure as well as the information within. Every database creates an MDF file by default & users can create multiple MDF files as well. Understanding both file formats can help users convert SQL BAK file to MDF smoothly.
How to Create BAK File in SQL Database?
Users have a few ways to create a backup of the database in the SQL Server using SSMS or command line method. Here, we’re going to explain the easiest way possible so that there will be no errors in the entire operation.
