 Azure Backup for AKS currently supports the following two options when doing a restore operation when resource clash happens (backed-up resource has the same name as the resource in the target AKS cluster). You can choose one of these options when defining the restore configuration.
 
-- **Skip**: This option is selected by default. For example, if you have backed up a PVC named *pvc-azuredisk* and you're restoring it in a target cluster that has the PVC with the same name, then the backup extension skips restoring the backed-up persistent volume claim (PVC). In such scenarios, we recommend you to delete the resource from the cluster, and then do the restore operation so that the backed-up items are only available in the cluster and aren't skipped.

 # Tutorial: Enable Vault Tier backups for AKS and restore across regions by using Azure Backup (preview)

+This tutorial describes how to create backups for an AKS cluster stored in the Secondary Region (Azure Paired region). Then perform a Cross Region Restore to recover the AKS Cluster during regional disaster.
 
-Azure Backup allows you to store AKS cluster backups in both **Operational Tier as snapshot** and **Vault Tier as blobs** (preview). This feature enables you to move snapshot-based AKS backups stored in Operational Tier to a Vault-standard Tier. You can use the backup policy, to define whether to store backups just in Operational Tier as snapshots or also protect them in Vault Tier along with Operational. Vaulted backups are stored offsite, which protects them from tenant compromise, malicious attacks, and ransomware threats. You can also retain the backup data for long term and can do Cross Region Restore by configuring the Backup vault with storage redundancy set as global and Cross Region Restore property as enabled. [Learn more](azure-kubernetes-service-backup-overview.md).
