Deleting data saved by system restore on Vista

Posted on 2008-10-17
Last Modified: 2012-05-05
I have an external storage array called a Drobo (www.drobo.com) on which I save my photos (I am a photographer).  I have been seeing the drive information raising even though I am not adding any information.  

First I checked the system restore for the third time.  It was shut off for the V: drive.  What I didnt notice was the time of the last restore.  lol  It seems it is making shadow copies of my drobo even though I have it turned off.  thanks vista!!

So to confirm this my friend had me do this at the cmd prompt.

C:\Users\savone>vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool

Shadow Copy Storage association
   For volume: (C:)\\?\Volume{a4c7e53f-c607-11db-b0e9-806e6f6e6963}\
   Shadow Copy Storage volume: (C:)\\?\Volume{a4c7e53f-c607-11db-b0e9-806e6f6e69
   Used Shadow Copy Storage space: 36.227 GB
   Allocated Shadow Copy Storage space: 37.611 GB
   Maximum Shadow Copy Storage space: 38.173 GB

Shadow Copy Storage association
   For volume: (V:)\\?\Volume{ef63054a-3753-11dd-aa00-001a925bfe63}\
   Shadow Copy Storage volume: (V:)\\?\Volume{ef63054a-3753-11dd-aa00-001a925bfe
   Used Shadow Copy Storage space: 226.935 GB
   Allocated Shadow Copy Storage space: 227.224 GB
   Maximum Shadow Copy Storage space: 307.2 GB

Drobo being my drive V.  This means I have 226 GB used on the drobo from system restore even though I have it unchecked in the settings.

383 - 151 = 232 which confirms this is my problem.

Now I need to find out how to delete all tha 226GB of system restore information saved on this drive to regain the storage space.  

I tried:

C:\Users\savone>vssadmin delete shadows /for=v: /all
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.

Error: Invalid command.

Any ideas?

Disk cleanup will permit all but the most recent copy to be removed. Select Files from all users on this computer, then the More Options tab. Here you can remove all but the most recent restore/shadow copy.

I have all but the last one deleted.  Is there anyway I can get rid of that last one?  It really bothers me knowing I have a wasted 6GIGs of space.

The restore files are in the folder X:\System Volume Information\restore{xxxx}. If you can get in here in safe mode you may be able to delete them. This method of doing this is not simple as the location is protected and Vista really doesn't want you there. First go to Control Panel Folder options and unhide operating system files. Now you can see the System Volume Information folder. Right click, go to Security and give yourself full permissions. In live mode with Restore on (as my system is) it won't give you permissions to the files, but it might if Restore is turned off, particularly in Safe mode. You will be able to enter the directory and see the files. Give it a try I guess.

Ok one more thing guys and gals.  I have system restore set for drive C (not for V which is the drobo).  and it still keeps writing info to the drobo.  The only thing I can think of is that I have My Documents target moved to a folder on the drobo.  Could this be the reason it is creating shadows on my V drive even though I have it unchecked in the System Properties>System protection dialog box?

Don't know. Move docs back to C to prove it one way or the other.
