The truncate_only operation has been deprecated in SQL Server 2008. There is no replacement. The log is automatically truncated when the db is in simple recovery. There are more details in Books Online.

Please read what Books Online says about Transaction Logs, and what a transaction log backup means.

The command you want to do does not take a backup of the transaction log. What it does do is discard the transaction log data.

Backup log Test with Truncate_only

and Why do you want to do this anyway:-P? That's a disaster.

We used the truncate_only functionality for development and test databases. For some load tests we take production databases to our test system. Our test environment is not as large as the production. The data within this databases are completely unimportant. After those tests the databases have been deleted. To safe disk space this was quiet helpful.

Sure in a production environment this is no option.

Hi,

I have multiple SQL 2008 production environment, and also Mirroring / Log Shipping enabled. Hence, changing the database to "simple" recovery mode is not possible. Hence, I wrote this code,

-- Replace the "DatabaseName" with Name of the Database

Use DatabaseName

go

SP_helpDB DatabaseName

Go

---Get the Log FileName and replace "LogFileName"

DBCC ShrinkFile(LogFileName,1)

Go

Backup Log DatabaseName with Truncate_Only

Go

DBCC ShrinkFile(LogFileName,1)

Go

Backup Log DatabaseName with Truncate_Only

Go

DBCC ShrinkFile(LogFileName,1)

Go
