1 Ensure Volume Shadow Copy Status is Running and Automatic in Services.MSC

Checking the UpperFilters Parameter

UpperFilter values exist in different registry classes and if they are configured incorrectly it can cause an issue during the restore process. Therefore, in this step, we will be checking to see if they are entered properly. For that:

1. Press “Windows” + “R” to open Run prompt.
2. Type in “regedit” and press “Enter“.
