Restoring PVC Backups

Backups created in MyNWS are not displayed in the Kubernetes cluster and therefore have to be restored in a different way. To create a new PVC from a backup, the following steps must be performed.

Preparation

For the restoration you need a bash shell with kubectl and a correct kubeconfig. You also need the name of the backup in order to perform the restore in OpenStack.

backup-view

In this case the backup highlighted in yellow is used for the restore. It should be restored into the production namespace.

The script restore.sh must be placed on the client and made executable.

Execution

The script is interactive and asks all necessary questions for the restore.

chmod +x ./restore.sh
./restore.sh
