    How to Change Maximum Disk Space Used by System Protection and System Images in Windows 8 and 8.1

    information   Information
    System protection is a feature that regularly creates and saves information about your computer's system files, programs, drivers, and registry settings as restore points for all drives that have system protection turned on. You can use these restore points to do a system restore to return these items to an earlier point in time without affecting personal files (ex: anything in C:\Users\(user-name) folder). Restore points are created just before significant system events, such as the installation of a program or device driver. They're also created automatically by Windows using a scheduled task once every seven days if no other restore points were created in the previous seven days, but you can create restore points manually at any time.

    To store restore points, you need at least 300 MB of free space on each disk that is 500 MB or larger. By default, system protection might use between 3-5 percent of the space on each disk that system protection is turned on for restore points. As the amount of space fills up with restore points, Windows automatically deletes older restore points to make room for new ones. System protection doesn't run on disks smaller than 1 GB.

    This same setting also determines the maximum disk space that can be used to store system images on a drive letter. The size of a system image can be quite large since it will include all system drives in the image by default plus any drives you have included. If you want to keep multiple system images, be sure to increase the max size accordingly.




    This tutorial will show you how to manage and change the maximum disk space you want to be used for system protection restore points and system images in Windows 8 and 8.1.

    System Restore isn't available for Windows RT.

    You must be logged in as an administrator to be able to change the maximum disk space used for system protection and system images in Windows 8.

    I am running the new Windows 8.1 preview (64 bit). The computer keeps deleting my Restore Points. I have set the configure setting to about 10% of my SSD space (10 gig or so). I can create the restore points, however, after a day or so and some re-boots I either have no restore points or maybe 1. The allocated space keeps getting re-set to 0 bytes.
    When I was using Win 8 all was working fine. Any suggestions?

    Hello John, and welcome to Eight Forums.

    Do you dual boot with any other OS, or use any type of 3rd party disk defragmenter program?

    Could you also post a screenshot of your System Protection settings like under step 8 in Option One after it's reset to see how they look?

    Thanks for the fast reply. I have two ssd's, one with Win 7 64 bit hp, and one with Win 8.1 pro 64 bit. I am using a Asus Maximus V Gene and a Intel I5 3570k along with 16 gig of ram. Also installed is a Asus/Nvidia 660 graphics card. I am not dual booting. The operating systems each reside on their own seperate SSD and were installed with only one SSD connected at a time as not to cross pollute. I use Easy BCD to select witch operating to boot into. I do not defrag the SSD's. I will use the Intel or Samsung trim utility about once per week. I will post screen shots later as my wife is using the computer now and I'm on my I Pad.Thanks.

    Not sure if the trim utility is wiping the shadow space on the HDD, but that would be something to look at to see if it happens right after using it.

    Since you do multi-boot with W7 and W8, check to make sure that you do not have system protection turned on for the other OS's HDD while in each OS.

    I will check on the trim function. Since my operating systems are on seperate ssd's does that mean I'm really dual booting? There is no indication of that on either operating system. However, the Win 8.1 pro does list the Win 7 system in the restore point configure window. I will try configuring the restore function on only one system and choosing to protect the other SSD.

    You'll need to have System Protection set to be turned off that way in both Windows 7 and Windows 8 for only the other.

    I have a problem with my restore points.
    Yesterday in the evening I checked my restore points for my C partition an saw that almost all of my created restore points in the past few days are deleted. I had only 3 restore points and they took 10GB, this is at least twice as much as the max usage (I had set the max usage at 4.67 GB)
    I have deleted the restore points and have set the max usage at 10GB.

    Right now the restore points are taking a few 100 MB, I have created a new restore point yesterday after deleting the other restore points and I have just created a new restore point.

    It is just like the restore system is ignoring the max usage and deletes restore points whenever it likes.

    This happened a couple of times since I've noticed it.

    Hello Martijn,

    Did vssadmin list shadowstorage show the correct size?

    Do you have any 3rd party utility programs installed that may be deleting them?

    If you dual boot, it can delete restore points when starting the other OS.

    Vssadmin list shadowstorage shows the correct size.

    With 3rd party program you mean something like Ccleaner?

    I have no dual boot, wouldn't be smart since I play a lot with the spaces.
