Dell PowerProtect Data Manager Appliance 5.12.0.1 Kubernetes User Guide

Disaster recovery considerations

Remember that application templates can be deployed to the PowerProtect namespace or to a user-defined namespace. The application template is a required component for working with application-consistent database backups.

When backing up a user-defined namespace, the PowerProtect Data Manager Appliance also backs up the application template from the user-defined namespace. The template is thus preserved if a disaster strikes.

However, application templates in the PowerProtect namespace are not backed up and are not automatically preserved. If you deploy an application template to the PowerProtect namespace, you must manually copy or back up these templates yourself. This manual copy preserves the template source in the event of disaster.

After the disaster, complete the following tasks:

1. Recover the Kubernetes cluster through the normal disaster-recovery procedure.
2. Manually restore the templates to the Kubernetes cluster.
3. Redeploy the templates from the backup to the PowerProtect namespace.
