You can use a file to modify the default values for Medusa, and then apply these changes during install, or by performing an upgrade. In the configuration file, you can specify parameters like the storage mechanism, the bucket name and the secret containing the storage credentials.

There are three steps to setting up Medusa within K8ssandra:

With the storage manager setup, the secret created and the configuration file organized, you then use Helm to install or upgrade your K8ssandra cluster configuration.

There are three steps to setting up Medusa within K8ssandra:

1. Set up a storage manager such as AWS’s S3 and create a bucket (i.e., a storage container within the storage manager).
2. Create a Kubernetes secret containing the credentials for the storage manager.
3. Create a Helm configuration file that enables Medusa, and identifies the storage manager, the corresponding secret that contains the credentials for the storage manager, and the target bucket within the storage manager.

Within K8ssandra, you use Helm to perform backup and restore operations. The backup and restore Helm operations are part of the same Helm chart used to install K8ssandra. To perform a backup, you install a Helm release, which creates a CassandraBackup resource representing your backup data. Since your backup data looks like a CassandraBackup CRD, you can use kubectl to list these objects.

A restore command looks a lot like a backup command. It uses Helm with a couple of different options, such as the restore helm chart name and the backup.name option to identify the backup data.
