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 https://www.ms4u.info/2023/12/unable-to-restore-ocp-v-vm-from-s3-when.html .

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]

Direct Restore to GCP Test Result

 Here is my lab environment test result on Direct Restore to GCP.

Note: Does not represent the real scenario. Recommend testing on your environment to get the exact result.

The below sharing is just for test purposes

Bandwidth used:

• Download: 800Mbps
• Upload: 200 Mbps

a) Restore from on-prem backup target to GCP

Using worker e2-micro

Using worker c2d-highcpu-2

b) Restore from GCP object storage to GCP

Using worker c2d-highcpu-2

Conclusion: 

• More faster when backup data resides on GCP object storage
• Changing to the higher spec of worker does not improve the restore speed

Install Older Version of Kasten

You may come to a situation where your customer is running an older version of Kubernetes. Example v1.22. Then you want to back up the container using Kasten.

When you run preflight check, the result indicates "Unsupported"

When we checked the user guide: https://docs.kasten.io/6.0.8/operating/support.html,

Minimum version support is v1.24

[Workaround]

Kasten version to support v1.22 is Kasten 5.5.9

https://docs.kasten.io/5.5.9/operating/support.html?highlight=1%2026

Command to install particular version

helm install k10 kasten/k10 -n kasten-io --version 5.5.9
