I'm trying to set up AWS Backup for EC2 instance with Windows Server 2022 and MS SQL Server, following this instruction https://docs.aws.amazon.com/aws-backup/latest/devguide/windows-backups.html I've done all the steps, but the on-demand backup job finishes with the message:
"Windows VSS Backup attempt failed because of timeout on VSS enabled snapshot creation"
The file "C:\Program Files\Amazon\AwsVssComponents\vsserr.log" is empty, "C:\Program Files\Amazon\AwsVssComponents\vssout.log" contains information about Shadow copies of devices and ends with the message "Snapshot creation done."
There are several messages related to VSS in Windows Log, for example:
Volume Shadow Copy Service error: A critical component required by the Volume Shadow Copy service is not registered. This might happened if an error occurred during Windows setup or during installation of a Shadow Copy provider. The error returned from CoCreateInstance on class with CLSID {4baeabae-7018-43e6-8bfb-fb15aaa3a675} and Name SW_PROV is [0x80040154, Class not registered
].
Operation:

Add a Volume to a Shadow Copy Set
Context:

Snapshot Context: 2
Snapshot Context: 2
Execution Context: Coordinator
Provider ID: {00000000-0000-0000-0000-000000000000}
What else can be checked and how to fix the timeout error?
Error : Windows VSS Backup attempt failed because of timeout on VSS enabled snapshot creation.
