SBS using all hard drive space

SBS 2008 SP1 on a 80gb partition. notmally has 29gb free space.
Server has started to run extreemly slow. Noticed one day that the C: was completely full. (and I mean completely full with 0mb of free space)

After cleaning my drawers :>) started frantically trying to make a little room, but it was using it up as soon as I'd free up some space. Drove out onsite, about an hour away, and in that time the free space was back to normal.... but the server is still slower than usuall.

Since then I have been watching the server more closely, and see that the free space swings from 29gb to 10gb randomly throughout the day and night. Luckly I have not seen a 0mb day.

Windows backups have started failing too add to the problem.
Who is Participating?

I ran into some issues with this in the past. The main culprits are:

System Restore / Volume shadow copy / Previous Versions (which saves all its data on the C:\ drive and for some reason has no maximum defined by default). The second culprit is sharepoint database LDF files (which seem to slowly grow over time regardless of whether you use sharepoint or not), and sometimes also archived WSUS patches and files (which you can't do much about but it slowly grows)

Windows SBS has two notorious things that consume large amounts of disk space:

1) Volume Shadow Copy / "Previous Versions" / System Restore

 - For some reason the C:\ drive on SBS 2008 has an "unlimited" quota for System Restore / volume shadow copy. Go into Disk Management and change the limit.

part 2 of this guide is relevant:

2) Sharepoint SQL database log files

- This is more tricky to do. You'll need to google for some guides that are relevant to your particular situation, but this well help get you started:

Unless your network is bandwidth limited I'd suggest changing the WSUS options to NOT download the updates or if you can't do that then change the location to a drive that has a lot of space ( 500G) or they will quickly overfill the meagre space you've set up the server to work with.

There may be more than WSUS at work here.  You can use the native WSUS application, under Administrative Tools, to clean out the debris from WSUS.   But for a deeper look, download and "run as adminstrator", either tree size pro or windirstat.  Running as administrator will find stuff that would not normally be exposed.

You should also use the SBS Console wizards to move all user and growing date to a larger partition.

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

ok... so wsus service is disabled
Sharepoint is disabled
Shadow copies are disabled on all drives.
exchange is disabled.
System partition size still is swinging wildly from 29 to 10 gb

performance is extreemly slow for file sharing or navigating at the server.

Windows backup still fail.

Windows update hangs at looking for updates.... just never finishes.

I'd open a case with Microsoft, but don't know where to start.
David Johnson, CD, MVPOwnerCommented:
how much physical memory?

80G is still rather small.. especially since normally SBS holds the user profiles as well
Larry Struckmeyer MVPCommented:
What did you find with the utilities I listed earlier?  What files are changing size?  I have not experienced this with any of the servers we manage, and have not seen in here or in other forums.  

You may have an unwelcome visitor, so I suggest a thorough scan with a different AV and Kerpaskeys's TDSS Root Kit Killer.

Since all the services are stopped it would be a good time to do this, but be doubly sure you have a known good restorable backup first.

Sorry for the long delay...

Anyway, found the culprit.... Microsoft internal database or MICROSOFT##SSEE instance.
Killed it, Uninstalled it, and everything is back to normal.

Thanks for the comments guys.... even though the problem was not directly addresses, your comments got me looking in better directions.
David Johnson, CD, MVPOwnerCommented:
That is your WSUS database
Larry Struckmeyer MVPCommented:
IMO, this was not a good idea.

All growing data... WSUS, Exchange, user redirected folders and so on, should be moved to the data partition.  The system partition needs its space, but SBS needs to have its resources and services to be used as it is meant to be used.  With WSUS not functioning you have reverted to an unmanaged network, at least as far as updates are concerned, with users either not updating or potentially applying updates that should not be.
