Backup config integration

This guide describes how to integrate Charmed Velero with client charms.

Requirements

• Charmed Velero deployed and configured.
• The client charm exposes a velero_backup_config endpoint.

Same-model relation

juju integrate <client-app>:velero-backup-config velero-operator:velero-backups

The client publishes its backup spec over the relation; the operator consumes it.

Cross-model integration

Charmed Velero can serve multiple models using Cross-model integration (CMI).

You can offer the Charmed Velero relation from the model where the charm is deployed:

juju switch velero
juju offer velero-operator:velero-backups velero-backups

This creates an offer name, i.e., an alias, velero-backups. Juju prints a URL like: <controller>/<model>.velero-backups.

The offered relation can be consumed from a client model as follows:

juju switch <client_model>
juju consume <controller>/<velero-model>.velero-backups
