System Restore works sporadically
I'm running 20H2.
I've long had a scheduled task that is intended to create a restore point every so often. I noticed a few days ago that it was only creating a occasional restore points, and most weren't created when they should be.
The task uses the wmic.exe method:
Code:WMIC.exe /Namespace:\\root\default Path SystemRestore Call CreateRestorePoint "Restore Point Name", 100, 1
I see the same behavior manually as I get with the task: Usually, no restore point is created.
When I try using wmic.exe to create a restore point, the Application log always reports the following, even when no restore point is created:
Code:Successfully created restore point (Process = C:\WINDOWS\system32\wbem\wmiprvse.exe; Description = Manual Restore Point).
A few seconds later, though, this entry appears:
Code:Volume Shadow Copy Service error: Unexpected error calling routine QueryFullProcessImageNameW. hr = 0x8007001f, A device attached to the system is not functioning.. Operation: Executing Asynchronous OperationContext: Current State: DoSnapshotSet
Sometimes, I can get System Restore to work properly for awhile if I totally disable it for my Windows volume, and then re-enable it. But sometimes, even that doesn't work.
I've run chkdsk (no problems found) and sfc /scannow (no problems found).
Ideas?
