WSUS takes too much space on server

In a Windows SBS 2008, the WSUS databases and updates folder is taking a huge amount of space. How would I go about shrinking it? Would it cause any problem in the server if I would just uninstall it all together and find other venues for Windows updates?

Thank you for your help!

In WSUS run the Clean up wizard.  This will remove unneeded updates etc.

See TechNet article on the matter here -> http://technet.microsoft.com/en-us/library/cc708578(v=ws.10).aspx

Thank you for your fast response.

That solution wouldn't lower the mdf and ldf size of the database, would it?

The size of the actual database compared to the space used by the umpteen unused windows updates is negligible.

If you REALLY NEED the space back. Add another hard disk and migrate WSUS data to a new drive letter on the server.

I have not used this but here is a link to guide on doing exactly what you are asking. If you can test in a test lab first, all the better.

http://blogs.technet.com/b/sbs/archive/2009/09/23/how-to-move-wsus-content-and-database-files-to-a-different-partition.aspx

It walks you though using the SBS wizard to migrate the actual WSUS content and then MSSQL studio to move the databases.

The mdf file is at around 25Gb, while the windows updates folder is at 20Gb. I just inherited this server and it looks like the guy before me left it to grow out of control. We might not even use WSUS at all but I didn't want to just go in there and delete stuff or uninstall WSUS all together. We might have to do that but I just want to make sure it will not affect anything else on the server.

Just an FYI, the WSUS cleanup wizard only gains very minimal space back....Moving the content and database as suggested is the only way to go

Run on a regular basis yes but if, as the op suggests, this box has never had any maintenance run on it then it "Can" reclaim quite a bit.

Should I just uninstall it? I think it's an overkill to have it for 5 computers...

If never run, the length of time to run it is much better served by moving it :)

Uninstalling WSUS on SBS tends to break other things

So long as it is removed using SBS and not just deleted it has never caused me or anyone I know an issue.

I was just planning on doing it from 'Programs and Features'. Would that be a problem?


Thanks!

That should be fine. Just make sure you make a backup of the suscomp.dll file found in C:\Windows\system32\inetsrv otherwise your websites in IIS may start throwing HTTP 500 errors, including the Remote Web Workplace and OWA sites.
