Article from Microsoft that explains in detail about how to edit the drive letters for Windows Backup.

However, and yes I know there are a lot of free backup programs out there.  I use Acronis Backup and Recovery 10 on my Servers and Acronis TrueImage Home 2011 Plus for my home PC's.

I know they cost, but I have found that my life is a lot easier with these programs and I love Acronis Support.  They have been amazing to me and this is a shameless plug, but I do not work for Acronis.

This key "Backup" is not in my registry

Your KB is for SBS 2003 not for SBS 2008

Oops...sorry about that.

Try this article then:

And just because I feel like posting the pertinent info here for you...

"We've had a few customers that have purchased external storage devices as backup targets for their Small Business Server 2003 customers only to find that the new drive/device is not an option as a target for the Small Business Server 2003 Backup Configuration Wizard.  The SBS Backup Configuration Wizard will only expose physical drives/tape devices as valid targets for a backup, even though the external storage device has a drive letter assigned in My Computer.  Think of how Secure Digital cards (SD cards) or Compact Flash cards (CF cards) show up in Windows XP in My Computer.  Typically they show up under "Devices with Removable Storage".  You cannot select this type of media as a target for the SBS Backup Configuration Wizard.

The workaround is to run the SBS Backup Configuration Wizard and to select a physical drive as a target (the C: drive or D: drive for example, any physical disk will do).  If you select the C: drive (the system partition, where Windows is installed) make sure to click NO to "You have chosen to back up...Do you want to change the backup location?".  Once the Backup Configuration Wizard has completed, edit the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Backup\Backup Location Path

Change it from C:\Backups\Backup Files to X:\Backups\Backup Files where X: is the drive letter assigned in My Computer to the external storage device."

I realize that that the above also says 2003 but I did find a few more things for you:

And I also found a "Supported backup drive list" too:

I had this same issue on a 2003 SBS server and the above helped me solve my issue but apparently 2008 SBS is completely different they must have gotten rid of that registry key "hack...?"

Link to the supported drive list I found though:

No do not create the key in 2008.

MS changed the behavior to backup in 2008 completely from 2003.

I have been really searching through a lot of resources though my MS partner sites and I am really not finding much.

Which leads me back to asking you if using a 3rd party backup software is out of the question.  If it is then you will probably have to go to the supported drive list and select one of those drives.

Or you could try this:

Create a share for the drive, map a drive letter to the share then backup to the shared drive letter.

Sorry for my english!

The question is very simple.

In the regisrtry ¿How does change the default letter of the backup unit?

In SBS2008 obviously

Best reagrds.

I think this has gone beyond my level of knowledge about SBS 2008.

I am sorry but, I can't seem to help any more at this point.

I hope another expert here knows something that I do not which is very likely.

Hang in there, man.  We'll help the best we can.

Something random that I found again trying to help still....

This relates to your specific issue that you posted in your last post and mentions a problem with the VSS service.  The solution was to call MS....

Ok finally something good for you to try:

"The SBCW.log under "C:\Program files\Windows Small Business Server\Logs" will show the following error:-

There may be a corrupted scheduled backup task.   The backup tasks are located in the following directory: "C:\windows\system32\tasks\microsoft\windows\backup".


Please try the following steps:

1.  Go to C:\windows\system32\tasks\microsoft\windows\backup, take a backup of Microsoft-Windows-WindowsBackup file and then delete it.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

322756 How to back up and restore the registry in Windows

2. Open registry editor.

In Windows Vista and in Windows Server 2008, click Start, type regedit in the Start Search box, and then press ENTER.

If you are prompted for an administrator password or for confirmation, type the password or provide confirmation.

3. Navigate to HKLM/Software/Microsoft/Windows NT/CurrentVersion/Schedule/TaskCache/Tree/Microsoft/Windows/Backup.

4. Backup the key Microsoft-Windows-WindowsBackup and then delete it.

5. Rerun Configure Server Backup wizard in the SBS console."
