Unable to Restore OCP-V VM from S3 When Using Kasten v6.5

I've upgraded to Kasten v6.5. I was able to back up RedHat OpenShift Virtualization VM using Snapshot and S3. However was not able to restore from S3 using TransformSet which I have created on v6.0.12. You may refer to .

Reported as a bug for a future fix. 

The workaround is to create a transform when doing restoration. [Click on below to view in large mode]

Unable to Restore OCP-V VM from S3 When Using Kasten v6.0.12

In my environment, I have used Kasten version v6.0.12 to back up Redhat Openshift Virtualization Virtual machine. No problem on using snapshot however encounter an error when trying to restore from S3.

After troubleshooting, realized that S3 backup data is a reference to snapshot backup data which has expired/removed. Well, it is not supposed to and reported as a bug for the next release fix.

For a workaround, you need to create a TransformSet. Refer to the below diagram to configure it and apply it when doing a restoration. [Click the image to view in large mode]
