AWS backup VSS error: Windows VSS Backup job error encountered.

0

The original error was Volume Shadow Copy Service error: Unexpected error calling routine RegOpenKeyExW(-2147483646,SYSTEM\CurrentControlSet\Services\VSS\Diag,...). hr = 0x80070005, Access is denied. Operation: Initializing Writer Context: Writer Class Id: {e8132975-6f93-4464-a53e-....} Writer Name: System Writer Writer Instance ID: {1c8b51a2-d08e-4c99-91c2-...}

I added the Network Service with FullControl in Diag, and the event log doesn't have this VSS error anymore but I still get the VSS backup job error encountered. This Ec2 is a Domain Controller, file server with DHCP role and also have DFS enabled.

In my log, I think it required AWS powershell installed?

EC2 VSS Agent Version: 2.0.0.0 PowerShell version: 5.1.17763.2931 Get-AWSPowerShellVersion not found. All available PowerShell Modules matching AWS: End diagnostic information. {"Error":"1002","Failures":["Unable to locate AWS PowerShell tools"]}*

Yes, AWS Powershell tools are required for the current AWS VSS backup to succeed. You can find documentation on the installation process here: https://docs.aws.amazon.com/powershell/latest/userguide/pstools-welcome.html
