Setting up Velero plugins

You can back up your assets, such as Kubernetes objects and databases, in supported cloud providers:

Amazon S3: CloudCasa can use the storage interface for Amazon S3.
Microsoft Azure: Use either the Kubernetes Container Storage Interface (CSI) or the Velero plugin. For more details, see Setting up the Velero plugin for Microsoft Azure.
Google Cloud Platform (GCP): Use either the Kubernetes CSI or the Velero plugin. For more details, see Setting up the Velero plugin for Google Cloud Platform.
Other storage solutions: Contact CloudCasa Support: casa@cloudcasa.io. CloudCasa does not support or qualified storage solutions with the Kubernetes CSI or the Velero plugins except for Microsoft Azure and Google Cloud Platform.

That is, you should use the Velero plugin if you are using storage which does not support the Kubernetes CSI on Microsoft Azure or Google Cloud Platform so that you can protect your data in it by using CloudCasa.
