How to create and list backups
This guide contains recommended steps and useful commands for creating and managing backups to ensure smooth restores.
Prerequisites
- A deployed MySQL cluster
- Access to S3 storage
- Configured settings for S3 storage
Create a backup
Once juju status shows Charmed MySQL as active and idle, you can create your first backup with the create-backup command:
juju run mysql/leader create-backup
If you have a cluster of one unit, you can run the create-backup action on mysql-k8s/leader (which will also be the primary unit).
Otherwise, you must run the create-backup action on a non-primary unit. To find the primary, see juju status or run juju run mysql-k8s/leader get-cluster-status to find the primary unit).
List backups
You can list your available, failed, and in progress backups by running the list-backups command:
juju run mysql/leader list-backups
