        - id: $$cap_aws_endpoint
          label: AWS Endpoint
          description: This is the FQDN of your storage server, e.g. `storage.example.com`. Do not set this when working against AWS S3 (the default value is `s3.amazonaws.com`). If you need to set a specific (non-https) protocol, you will need to use the option below.
        - id: $$cap_backup_filename
          label: Backup filename
          defaultValue: 'backup-%Y-%m-%dT%H-%M-%S.tar.gz'
          description: The name of the backup file including the `.tar.gz` extension. Format verbs will be replaced as in `strftime`. Omitting them will result in the same filename for every backup run, which means previous versions will be overwritten on subsequent runs. The default results in filenames like `backup-2021-08-29T04-00-00.tar.gz`.

          defaultValue: '@daily'
          description: Backups run on the given cron schedule in `busybox` flavor. If no value is set, `@daily` will be used. If you do not want the cron to ever run, use `0 0 5 31 2 ?`.
        - id: $$cap_backup_retention_days
          label: Backup retention days
          defaultValue: '14'
          description: Define this value to enable automatic rotation of old backups. The value declares the number of days for which a backup is kept.
