# Backups
-
- ## Nextcloud
-
- Le backup export en utilisant la commande Export du Snap vers le
- répertoire par défaut et non changeable
- `/var/snap/nextcloud/common/backups`. Celui si est "symlinké" avec un
- répertoire sur les disques grandes capacités `/mnt/data/backup`.
-
- Le fichier obtenu est compressé et envoyé par rsync vers le NAS Synology
- FGM-ARBRE. Pour cela l'utilisateur rsync a été créé avec autorisation
- d'accès rsync, et répertoire de backup sur Arbre.
-
- Le répertoire de données Nextcloud `/data` est directement synchronisé
- avec son propre répertoire sur le backup d'Arbre.
-
- Les logs sont sauvegardés dans `/var/log/`.
-
- Les répertoires intermédiaires sont vidés avant traitement, les logs
- sont limités ansi que le nombre de fichier compressé de Nexcloud
- (database, paramétrages...)
