Does anyone know the reason for System Restore taking up more drive space after only a few days? I'm not making any new restore points but it still seems to increase in size.

For example, I make a restore point that's like 600 MB in size; when I check back in a few days, the used disk space from restore points has increased to 25 GB.

What is going on here? I'm running Windows 7 Home Premium.

What your seeing is space being taken up by both "Restore Points" and "Previous Versions" of files - both of which are stored in the same folder.

"Previous Version" file copies get made regularly by default in Win7.

What files actually get get backed up to previous versions? Is it really enough to use 30 GBs of disk space after only a few days? –  Aznfin Dec 31 '09 at 5:26
    
The Previous Versions affect practically every file/folder on the hard drives. Go right click a folder and select "Restore Previous Versions" and you'll see what shadows exist for that folder. The Previous version get cleaned up as you need the space, so they're not a big deal. My Win 7 system has about 30GB of space (12% of each drive) being used right now as well. Previous Versions has saved my butt a few times, it's worth it. ;) –  Ƭᴇcʜιᴇ007 Dec 31 '09 at 15:48
    
Perhaps I'll just keep system restore using 15% of my drive again. Now that I understand how useful previous versions can be. Thanks for the explanation it was just what I was looking for. –  Aznfin Jan 1 '10 at 16:03

Do you have automatic updates on?

Windows automatically creates restore points before updates are applied incase of failure (Which is good - Windows 7 is VERY good at recovering from failures).

After this, most installations now also create automatic restore points.

If this is a problem, you can look in Control Panel > System Properties (Windows Flag+Pause/Break), then click System protection on the left. Click the Configure button and you can manually control the space usage.

I don't have automatic updates on and usually when I check CCleaner for new system restore points after Windows Update and other installations I don't find any new restore points. –  Aznfin Dec 31 '09 at 4:17
    
Then how do you know it is system restore taking up the space... Where are you seeing this? Can you post a screenshot? –  William Hilsum Dec 31 '09 at 4:37
    
Well I check System Restore > Configure in system properties and view the used disk space. It just magically increases for some reason. I also tend to check my hard drive a lot and my free space decreases. When I comes to disk space I'm always looking for ways to free up used space. –  Aznfin Dec 31 '09 at 4:44
