Minimum size of system restore

Hi! Noob question here – what would be the minimum size that tech people would recommend for system restore to function properly? Thanks in advance!

Regularly, restore point has about 600MB, But it comes down how many restore points you want to be able have available.

Hi @Dav21,

I usually set to 10% which means if the partition has 200GB than it will take 20GB for the system restore. It can store 4 or 5 restore point or it depends on the partition usage size.

Pro Tip. I use the below PowerShell script in the startup using task scheduler which will enable the system restore if it disabled and set the maximum size to 10%.

enable-ComputerRestore -Drive “c:”

vssadmin resize shadowstorage /for=c: /on=c: /maxsize=10%

checkpoint-computer -Description ‘System Restore Point’ -RestorePointType modify_settings


you need at least 300 megabytes (MB) of free space on each disk that is 500 MB or larger. “ System Restore might use between three and five percent of the space on each disk

hello @Dav21

I hope this link will help you

I think minimum size of system restore for windows 10 with basic apps and programs will be in between 1 GB to 2 GB.
