--- title: Sauvegardes taxonomy: category: - docs --- Pour la sécurité en cas de besoins de restauration des données: Nous avons des sauvegardes locales journalières des données et du système sur le volume `/mnt/backups/borgarchives` de 1 To avec avec [Borg App](https://github.com/YunoHost-Apps/borg_ynh), plus une sauvegarde journalière (aussi avec Borg App), chiffrée sur un serveur Yunohost auto-hébergé où est installé [Borg Server](https://github.com/YunoHost-Apps/borgserver_ynh) sur un disque dur de 2 To. > ! Il est tout de même conseillé malgré toutes ces précautions aux utilisateurs qui ont des données sur Nextcloud (Cloud Linux07) de bien faire des sauvegardes de temps à autres. Nous ne pouvons pas garantir à 100% de ne jamais rien perdre, mais nous faisons tout notre possible pour éviter de risquer de perdre vos données.
