Truncate Log on a SQL Server 2012 Database

I have a SQL Server 2012 DB in Full recovery mode that has never had a TLOG backup.   the log is huge 200+GB.

I tried doing a transaction log backup but there is not enough space on the Disk.    

How can I reclaim this log space in SQL Server 2012?

One way to do it would be to change the backup method to "Simple" then shrink the file.

ALTER DATABASE mydatabase SET RECOVERY SIMPLE
 DBCC SHRINKFILE (mydatabase_Log, 1)

Open in new window


The only thing is that might also require disk space.

You could create a new database, copy the schema, then import the data, then delete the old database. That'll be a pain but it would work with minimal disk space requirements.

Easiest is to change recovery to SIMPLE -- so you don't have to take a log backup -- then do a CHECKPOINT(s).  You go back to FULL later if you want to.

USE <db_name>
ALTER DATABASE <db_name> SET RECOVERY SIMPLE
CHECKPOINT
DBCC SHRINKFILE ( 2, 4096 ) --leave 4GB in the log file
