| The Backup File Extension I run this command in SQL Server 2022. What is the extension of the backup file? BACKUP DATABASE HerdofTwo TO DISK = 'HerdOfTwo_20240501'Answer: there is no extension Explanation: The convention for SQL Server database backup files is to use .bak, and in very old versions (4.2) .dmp. However, this is convention. There is not requirement for this extension to be used, nor is one required. In this case, no extension is provided, so the file is created without any extension. This is not documented, but try it. You can create a backup without any extension. |
