    How to Change System Protection Maximum Storage Size for Drive in Windows 10


    System protection (if turned on) is a feature that allows you to perform a system restore that takes your PC back to an earlier point in time, called a system restore point. This can be handy if your PC isn't working well and you recently installed an app, driver, or update.

    Each restore point contains the necessary information needed to restore the system to the chosen state. Restore points are automatically generated when you install a new app, driver, or Windows update, and generated when you create a restore point manually. Restoring won’t affect your personal files in your %UserProfile% folder, but it will remove apps, drivers, and updates installed after the restore point was created.

    You can adjust the maximum disk space per drive used for system protection. As space fills up, older restore points will automatically be deleted to make room for new ones.

    This tutorial will show you how to resize the maximum shadow copy storage space used by system protection for a drive in Windows 10.

    You must be signed in as an administrator to be able to change maximum shadow copy storage size.

    Restore points are stored in the hidden protected OS System Volume Information folder in the root directory of each drive you have system protection turned on.

    OPTION TWO

    To Change System Protection Maximum Storage Size for Drive in Command Prompt


    1 Open an elevated command prompt.

    2 Copy and paste the command below into the elevated command prompt, and press Enter. This will show you the current maximum usage size for all drives that have a shadow copy storage space. (see screenshot below)

    vssadmin list shadowstorage

    3 Type the command below into the elevated command prompt, and press Enter. (see screenshots below)

    vssadmin resize shadowstorage /for=<ForVolumeSpec> /on=<OnVolumeSpec> /maxsize=<MaxSizeSpec>

    Substitute <ForVolumeSpec> in the command above for the actual drive letter (ex: C: ) that the shadow copy storage is for. This will be the For volume in the results from step 2.

    Substitute <OnVolumeSpec> in the command above for the actual drive letter (ex: C: ) that the shadow copy storage is on. This will be the Shadow Copy Storage volume in the results from step 2.

    Substitute <MaxSizeSpec> in the command above for the actual size you want.

    The MaxSizeSpec value must be 1 MB or greater and must be expressed in % percentage or one of the following units: KB, MB, GB, TB, PB, or EB. If no unit is specified, MaxSizeSpec uses bytes by default.

    If no value is specified for /maxsize, there is no limit placed on the amount of storage space that can be used.

    For example:

    vssadmin resize shadowstorage /for=C: /on=C: /maxsize=12GB

    OR

    vssadmin resize shadowstorage /for=C: /on=C: /maxsize=5%

    4 When finished, you can close the elevated command prompt if you like.


    That's it,
    Shawn

    Is there a way to set it as zero B/MB/GB or 0% for all drives at once like vssadmin delete shadows /all /quiet?
    If not it might be a good idea to make a batch file to loop through all drives to do so... )

    It really depends on your personal needs for how many restore points you would like to keep available, and how much free hard drive space you have available to reserve for restore points.

    Each restore point uses around 600 MB on average, but can vary.

    Please explain the "Allocated" spaces, and their reported amounts.

    Hello,

    The "allocated" space is how much space is currently reserved to be used. It can get as high as the set maximum.

    I stopped using restore points in early versions of W10 when it failed to restore when I really needed it....
    It may have become better now. But I will never trust it 100% anymore.

    But on what basis is any current allocated amount determined?

    It's determined by Windows based on your current usage.

    In first of the two cases shown in your screenshot www.tenforums.com/attachments/tutorials/53134d1449864290-change-system-protection-max-storage-size-drive-windows-10-a-vssadmin_list_shadowstorage.png ,
    allocated amount differs from current usage.
    In second case, the amounts are almost same.
