no regular backup configuration option

[Tom Haddon]

The percona-cluster charm doesn't currently have any backup options, so you have to manually configure backups if you're using it (i.e. outside of Juju). The mysql charm has the following options:

    backup_dir:
        default: "/var/lib/mysql/backups"
        type: string
        description: "Directory where backups will be stored"
    backup_schedule:
        default: ""
        type: string
        description: |
          Cron schedule used for backups. If empty backups are disabled
    backup_retention_count:
        default: 7
        type: int
        description: Number of recent backups to retain.

Obviously there may be some other needed options to figure out how/where to do backups when you have multiple units.

Note that the pxc charm does have an action to perform backups (thanks to the bootstack team for that).

That said, might be nice to have this feature as well.
