+La tâche _backup_ va permettre de sauvegarder les applications Yunohost ainsi que leurs données grâce à la mise en place d'une tâche cron. Cette sauvegarde utilise celle fournie par [Yunohost](https://yunohost.org/fr/backup) et elle est locale au serveur.
 
 - `ynh_backup.scheduled` : active la fonctionnalité de sauvegarde des applications Yunohost, mettez la valeur à `True`.
 - `ynh_backup.directory` : le dossier de sauvegarde par défaut est `/home/yunohost.backup/archives` cependant vous pouvez tout à fait choisir de sauvegarder les backups dans un autre dossier grâce à cette variable. Dans ce cas, de manière à pouvoir restaurer les backups depuis l'interface web, Yunohost créé automatiquement un lien symbolique de l'archive créée vers son dossier par défaut.
 - `ynh_backup.scheduled_[hour|minute|weekday|month]`: modifie la planification de la tâche cron. Par défaut elle se déclenchera tous les jours de l'année à 1 heure du matin. Pour plus d'informations concernant les réglages horaires cron, cet outil peut être utile : <https://crontab.guru/>.
 - `ynh_backup.system` : est obligatoire. Activez la sauvegarde du système Yunohost en mettant la valeur à `True`.
 - `ynh_backup.apps` : est obligatoire. Activez la sauvegarde des applications Yunohost en mettant la valeur à `True`.
-- `src_script`: il s'agit du chemin absolu où le fichier de template se situe sur la machine qui exécute Ansible. Par défaut, il sera stocké dans `templates/ynh_backup.sh.j2`.
-- `dest_script`: il s'agit du répertoire où le fichier de template va être stocké. Par défaut, il sera stocké dans `/usr/local/bin/`. Le script s'appelle `ynh_backup.sh`.

 - `ynh_backup.directory`: the default backup folder is `/home/yunohost.backup/archives` however you can choose to save the backups in another folder with this variable. In this case, in order to be able to restore the backups from the web interface, Yunohost automatically creates a symbolic link from the created archive to its default folder.
