SharePoint 2010 Content database growing too fast

Question

Hi,
I have a SharePoint 2010 Content database wss_content_DB which is 197 GB BUT when I calculate my site collection I can see they have used only about 70 GB. I know there is Auditdata table which is about 27 GB. Couple of days ago my content DB was about 105
GB and it Audit data log was set to unlimited once  I noticed that I set to 90 days since then it jumped to 197 GB.
 I have no idea what is going on.
 Now I need to know
 - why it is showing 197 GB in SQL server
 - How can I trim audit log
 -  Why suddenly it's increased to 197 GB from 105 GB
Any help will be greatly appreciated.

There is a way to deal with this table. There is an stsadm command (stsadm -o trimauditlog) as part of the infastructure update that will allow you to manage this data.
#Powershell Script to trim old AuditData table records.
$currentDate = Get-Date
#Number of days we want to keep data in the table
$NumberOfDays = -90
$DateToDelete = $currentDate.AddDays($NumberOfDays)
$DateString = ‘{0:yyyyMMdd}’ -f $DateToDelete
$STSADMCMD = “stsadm -o trimauditlog -date $DateString -databasename WSS_ContentDB”
invoke-expression “$STSADMCMD”
WHY IT SUDDENLY INCREASED:
Do this query on your SQL Instance: DBCC SQLPERF(logspace)
This will show you how the size of LOGfiles (LDF) and how much is unused, if you have alot of unused space it indicates you dont have a recent DB backup - normally backup would write log data to MDF file .
Normally you will not shrink DBs, only if you have deleted alot of data and you are not going to use space again so only do a shrink if you REALLY needs to.
