Actually you only start losing the older restore point as you reduce the size. The operation will tell you that as you reduce size. You will still have you most current files/restore points, you'll just start losing the older ones. I just did this operation a few days ago on my SSD drive

We all have different suggestions. I was explaining why he's also losing space, and a way to slow it down or stop it. I also recommended against completely turning it off.

Thanks.

You are right - it keeps the most recent one. I shall add that to my post.

Are you sure those ghosted copies take up any space at all?
Yes, I noted the amount of locked blocks on the partition with O&O, both before and after uninstalling the ghosts, and there was much less locked space afterward.

Interesting - I did not know that. Thanks for the info.

Here is a quote from O&O Defrag's help file"

Quote:
At the moment of installation Windows Vista (or newer) the shadow copy mechanism is set as default. With Windows XP64 and Windows Server 2003/2008 systems it is deactivated by default.

During defragmentation, files on a volume get moved. Vista perceives this as a deletion and creates a new Shadow Copy for the moved file. Because defragmentation requires the moving of multiple files, many Shadow Copies are created, which in turn leads to the higher demand on disk space. This behaviour may overwrite older shadow copies with newer ones. Unfortunately, this can also lead to the deletion of the system recovery points! These consequences are most frequent when using the COMPLETE method.

Shadow copies are filed in the folder “System Volume Information” and cannot be defragmented. This can end up having a negative influence on the result of the defragmentation. There is, on the other hand, almost hardly any loss in performance caused by fragmented shadow copies. Although these files will be displayed as fragmented, they still have only a minimal influence on the operating speed of your system
If I'm reading this right, anything that alters the files within a shadow copy will make it invalid, and it then remains as a ghost, as I described.

I have never reduced the size of anything on my C:, yet I get a lot of ghosts, and the only shadow copy available when I try to do a System Restore, is a non-ghosted shadow.

Not sure if you're adressing me Seekermeister but I was strictly talking about "System Protection" as seen here.....



All I know it that as you reduce the size, it deletes the older save points. It also states that as the space fills up, it will delete the older save points as well.

I never used that method to control the shadow copies, only vssadmin in the command prompt, and even when I reduced the space to the least possible (I think that it was zero) it did not delete the old shadow copies, the only way that I could get rid of them was to uninstall shadow copy ghosts in the Device Manager as I described. Deleting ghosts had no effect on what restore points were available at all.

That is strange indeed. I lost my shadows each time I mucked around with them - and even without intervention at times. Fortunately I do not really rely on them because I have frequent images. But sometimes they are more useful than images.

Is your pagefile on C? If Yes, is the size variable?

I do not us tools like ccleaner... perhaps it is NOT set to empty any temp folders, but rather set to delete generic temp file extensions (which your encoder may not use).
