* Restore {kube} resources and persistent volumes for supported storage providers
* Backup {kube} resources and persistent volumes for supported storage providers.
* Restore {kube} resources and persistent volumes for supported storage providers.

User can leverage these fundamental functions to achieve user stories:

* Backup whole {kube} cluster resources then restore if any {kube} resources loss
* Backup selected {kube} resources then restore if the selected {kube} resources loss
* Backup selected {kube} resources and persistent volumes then restore if the {kube} selected {kube} resources loss or data loss
* Backup whole {kube} cluster resources then restore if any {kube} resources loss.
* Backup selected {kube} resources then restore if the selected {kube} resources loss.
* Backup selected {kube} resources and persistent volumes then restore if the {kube} selected {kube} resources loss or data loss.
* Migrate the backup to other clusters for any purpose like migrates production cluster to develop cluster for testing.

Velero consists of below components:

* A Velero server that runs on your {kube} cluster
* A `restic` deployed on each worker nodes that run on your {kube} cluster (optional)
* A command-line client that runs locally
