Server 2008 Hard Drive Space

I have a SBS 2008 server setup on a RAID 1 with 250GB total size. Windows is showing me that there is 11GB remaining, which is impossible since I am not using that much space. I ran an app called Folder Size which shows me that my C drive is only at 141GB. I can't find where the remaining 98GB are. I checked pretty much everywhere.

Please, can someone shine some light on this?

Swap space, and preallocated space for open files could easily make up the difference.  If you want an accurate number, put in a USB stick with linux on it and boot the system to linux temporarily.  This will do a safe read-only mount of the NTFS filesystems.

Then look at the files.  Since no databases or applications will be running on the windows RAID device you'll get a true picture of how much space is occupied.  it will also report hidden files which will not show up on windows explorer.  (Did you TELL windows explorer to even reveal all hidden/system files? If not you don't have a true picture of the files in the first place).

Can you post a screenshot of your disk management page? You can find it by running "diskmgmt.msc".

SBS uses lots of space already by design. For example it runs WSUS, which holds the updates not only for the server OS's, but also for any attached windows PC's (xp, vista32/64, windows 7 32/64 etc). Then there is exchange etc. There are also transaction logs for exchange etc. 250GB is small for an SBS server and if the server is used in a normal way that space will fill up really quickly in the background without anyone even noticing.

Newly released Acronis True Image 2019

In announcing the release of the 15th Anniversary Edition of Acronis True Image 2019, the company revealed that its artificial intelligence-based anti-ransomware technology – stopped more than 200,000 ransomware attacks on 150,000 customers last year.

It could also be shadow copies that's using up all the space.

Go to My Computer..
Right Click Drive C:
Click on the shadow copies tab
You can manage shadow copies from here.

Have you checked your system restore points?
Right click my computer..
click properties..
click system protection on the left. (not sure if this is the same in SBS)

First identify which files or folders might cause the low disk space problem:

    hibernation file - c:\hiberfil.sys
    memory swap file - c:\pagefile.sys
    Windows Error Reporting - C:\programdata\microsoft\windows\wer\reportqueue
    SharePoint Databases - C:\Windows\SYSMSI\SSEE\MSSQL.2005\
    Component Store - C:\windows\WinSXS
    Old LOG files - C:\inetpub\logs\LogFiles
    Windows Server Update Services - C:\WSUS

plus data related to Small Business Server 2008 or SBS 2011:

    Redirected Folders
    User Folders
    Exchange
    SharePoint Services
    WSUS depository

I would recommend visit above link and verify which program is consuming more disk space on the server.

1. My windows explorer is set to show all hidden files and folders
2. My exchange server is only 13GB
3. I do have shadow copies. One is disabled and one is enabled
4. This is not an upgrade from an older windows
5. I do have a daily backup
6. My pagefile is at 17GB
7. Hibernation is off hence there is no hiberfil.sys file
8. Report logs are 171MB (Size on disk)
9. SharePoint Databases is at 12GB
10. Component Store is at 11.6GB
11. Old LOG files is at 14.7GB
12. Windows Server Update Services is at 25.6GB
13. Redirected Folders is at 5.45GB

The rest of the folders are pretty small.

OK.
Please download SpaceSniffer from here: http://www.uderzo.it/main_products/space_sniffer/download.html

and run it as administrator.

It should show you the space used, including hidden/system files.

It shows that my folder redirection is at 65GB
The second biggest file is the pagefile
The third biggest folder is exchange
The fourth is the  log file

Dan CraciunIT ConsultantCommented:
OK, the question is: does the program show all space used? 220GB?

Cause on your initial post you used a program that showed only 141 GB used.

If SpaceSniffer shows all your used space, then we can go about business as usual: see where the biggest space hogs are and trim them.

If it shows still 141 GB used, then we have a bigger problem: space that is hidden from the OS, which can indicate malware.

Like I wrote at the beginning, boot to a USB stick with LINUX on it, and nothing can hide, not even malware.

SpaceSniffer shows 222GB are used.

OK, great. Now you know where all your space is (including those 98GB you missed).

I believe that was your original question?

Now how do I clean up my hard drive? Can I delete some of the log files? Can I decrease the pagefile and Windows Server Update Services?...
0
Dan CraciunIT ConsultantCommented:
Well, the first thing I would do is clean the folder redirection. Unless you have strict filtering you're bound to find some movies/music/pictures not work related.

Old (more than a month) logs are usually safe to delete, if your system is working fine.

As for the page file... depends on your usage. Monitor your server and check how much of it Windows actually uses. It's the only way to know if you can shrink it without affecting performance.

HTH,
Dan

What is the best way to turn off Music, Video and Picture redirection to the server?

Do I just go to the folder and delete those old log files?

My system is using ~10GB out of 16GB of memory at any given time.

Dan CraciunIT ConsultantCommented:
I would let the swap file as is.

You can't exclude files in redirection, BUT you can use File Server Resource Manager. Here's a nice article about it: http://blogs.technet.com/b/josebda/archive/2008/08/20/the-basics-of-windows-server-2008-fsrm-file-server-resource-manager.aspx
The feature you want is called "File Screening".

You probably should use that anyway, since it has the option of generating reports with largest files/folders, old/unused files etc. It can help you not ending up in this situation again.

HTH,
Dan

PS: yes, it works on SBS also. You can find it in Windows Components->Management and Monitoring Tools.

About the log files: yes, you go and manually delete them.

But, if you're paranoid like me, you back them up first :) That way, if something hits the fan, you can be relaxed: you have backups.

Exchange transaction logs get removed automatically after a successful full backup (provided you are using an exchange aware backup tool). If the backups aren't successful, or if you aren't doing full backups, they accumulate. So you should either find out why the backup wasn't successful and correct that, or make full backups regularly, or use a backup utility that is exchange aware, or if you really trust your backups, enable circular logging..

I use a built the SBS built in backup. My backups are always successful.

rindiCommented:
The built-in backup is exchange aware. But are you doing full or incremental backups? Only the full ones remove the logs.

I believe I am doing a full backup. I'll check tonight.
