SQL SERVER – SHRINK Log File using SHRINKFILE

if you want to shrink the log file, you would use SHRINKFILE command like.

DBCC SHRINKFILE(TestDBLog, 1)
GO

But in some cases (like production database), if you shrink log file by using above command, you won't get expected result. So, if you want to shrink log file to minimum size, take backup (*.bak) of entire database with SIMPLE recovery mode and then run the shrink file command.

Here is the code to backup the database and shrink the log file

BACKUP DATABASE [TestDb] TO DISK = N'C:\TestDb.bak'
GO
DBCC SHRINKFILE(TestDBLog, 1)
GO
