SQL2012 - Sharepoint Config Log File Size

Hi,
I have a client that is running a SharePoint database on a server2008r2. Sql is 2012.
The Sharepoint_Config transaction log file ldf is huge (120gb). The mdf file is only 200mb.

I have been researching the shrink file command, or shrink file via the SQL Server management Studio.
 I have ran a 'DBCC SQLPERF(logspace)' and the Log file space used  is only 2.7 % on this database.

Can anyone advise me this is safe to do? and is there anything I need to do before running shrinkfile on the ldf file? except taking a full backup of the database.

Thanks, Colin

It's safe to shrink it. This Log file bloat is quite common.

There are the below methods, or DBCC Shrinkfile...

If you have not run any Transaction Log backups, you will not be able to shrink the Transaction Log.  What I suggest:
1. Start doing frequent Transaction Log backups or if you are unable to do that then
2. Change the Recovery Model from Full to Simple and lose the ability to do point-in-time restores.

Only do a DBCC SHRINKFILE as a last resort as it is detrimental to the health of your Transaction Log and therefore your database.
