I want to know how we can backup AKS-HCI workloads on prem as well as on another region ? We have a solution for AKS as Velero and blob storage but does it backup AKS - on prem (Locally) ? If not , Is there any other option for AKS -HCI to backup on-prem solution
Regards,

Julian Hüppauff 336 Reputation points Microsoft Employee2022-06-23T09:03:57.75+00:00 Velero can be used to backup Kubernetes (regardless of the type AKS, native K8s, GKS, etc.)
According to the docs Velero is able to migrate the volume snapshots within the same cloud provider.
https://velero.io/docs/v1.6/migration-case/If Azure Stack provides the same storage provider, it should be possible to migrate it this way.

2022-06-23T13:12:38.79+00:00 Beside Velero Azure Disk Snapshots can be used:

https://video2.skills-academy.com/en-us/azure/storage/blobs/object-replication-overviewBut in general, it would be better to remove the state from the pods and move data to some managed services (Azure CosmosDB, SQL Database, etc.).
Those come with more backup options. -

There isn't any documented procedure of backing AKS on Azure Stack HCI to on premises storage. The procedure documented here backup-workload-cluster is for backing up AKS workload cluster backup or restore using Velero to Azure Blob storage.
I don't think there is any standard way of performing backup to on-premises. I will check with internal teams and update this thread.

Is there any update on this backup strategy in Azure Stack HCI for Arc Enabled AKS Clusters ?

Bott, Karsten 0 Reputation points2024-02-02T08:41:38.15+00:00 you nailed it. there seems to be a lot of misleading statements in the field, including the one from @jhueppauff . In fact, the AzureHCI AKS CSI Driver HAS NO volumesnapshot capabilities. Yes there is a concept of using sidecars, but that is a security concern. As you mentioned, the https://video2.skills-academy.com/en-us/azure-stack/aks-hci/backup-workload-cluster is pretty miss leading as it cannot be applied on premises. People seem to mix AKS on Azure Stack Hub with AKS on HCI ... different storage stacks from a provider perspective
