Hi Experts,

There is a lot of system files in the System Volume Information folder of a partition on which the Shadow Copies have been disabled. We tried to enable and disable Shadow copies again, usually it delete all these files but here not.

Any idea ?

Can you specify the scope of this command to delete only shadows of this volume ?

It returns this :

No items found that satisfy the query.

Very strange, I checked that VSS was not configured on other drives to store files on this one. I don't understand what happens, new system files are created almost every day...

Can you look into the directory on the corresponding drive and see whats in there and how the strructure of it looks like?

If you don't want to mess with the permissions of that folder you can boot from a linux cd like knoppix and look inside the folder from there.

There is some very big system files named with GUID.
I search in the registry and found that the second GUID which is common to all filenames is the on of the default VSS provider.

Hmmm than it really seems its VSS related stuff. Maybe windows maintaines a DB somewhere where all the stored VSS data is organized, similar as for the recycle bin. Sometimes recycle bin shows empty, but there are still thousands of files in the recycled folders. But its just a guess I'm not sure.

If it were my system i would perform a full backup (image) and would just delete all the files in system volume information. than turn VSS on again on that drive and testing if its working again.

if somthing broke and VSS wont work anymore i would put back the image. Else if its obviously working observing the situation for a while to se if there are side effects or not. If side effects restore the image.

Data.

I wonder if I delete theses files manually... what happens ?

How to check if it is linked with other partition shadows ?

Deleting it manually could cause NTFS driver problems. What I would suggest is to copy out the data from this partition - format the partition and copy back the data. This will delete these ghost shadow copy files.

Let's see if everything is OK tomorrow, it should be.
