System restore points are lost

Hi Tom,

I understand the frustration when Restore points are lost.

Restore points are saved until the disk space System Restore reserves is filled up. As new restore points are created, old ones are deleted. If you turn off system protection (the feature that creates restore points) on a disk, all restore points are deleted
from that disk. When you turn system protection back on, new restore points are created.

Perform steps mentioned below and see if it helps.

a: Press Windows key + X.

b: Then click Command prompt(Admin)

Type Vssadmin list shadowstorage
c: Take note of what the shadow storage allocation is on the drive you're having issues with.

d: Change the allocation by using the Vssadmin command, syntax:
vssadmin resize shadowstorage /On=C: /For=C: /Maxsize=1G (where Maxsize=the amount of disk space you've allocated to System Restore points. In my case it was 20 GB



e: In the case of the C: drive, the syntax would be VSSAdmin resize shadowstorage /On=C: /For=C: /Maxsize =20G, after increasing the size and rebooting my restore points were still intact and no longer being deleted.

Please revert if you have any issues with Windows in future.

 

lost system restore point

Two things that could pertain to this. First, older System Restore points do roll off the end of the list when the drive space allocated to system restore has been used up and new restore points are being created.

The second point is that system restore points are sometimes deleted when significant operating system updates include changes that are incompatible with files stored in those old restore point(s).

I'm presuming that you did tick the box in System Restore that says "show more restore points".

 

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
