L'outil de sauvegarde de YunoHost ne sauvegarde que les fichiers utiles et se base sur des scripts de restauration pour réinstaller les dépendances de vos applications. Autrement dit, le mécanisme de YunoHost revient à réinstaller, puis réincorporer les données.
|
||||
|
||||
Réaliser des images complètes du système peut être un moyen complémentaire ou alternatif de sauvegarder votre machine. L'intérêt est que votre système pourra être restauré dans l'état exact du moment de la sauvegarde.

Lo strumento di backup di YunoHost salva solamente i files utili e si basa su degli script di ripristino per reinstallare le dipendenze dei vostri programmi installati. In altre parole, il ripristino di YunoHost prevede in un primo tempo la reinstallazione del sistema e in seguito il ripristino dei dati.
|
||||
|
||||
Realizzare un'immagine completa può essere un metodo, complementare o alternativo, per un backup del vostro server. Il vantaggio sta nel fatto che il vostro server può essere ripristinato nella stessa configurazione presente al momento del backup.

YunoHost's backup tool only backs up useful files and relies on restore scripts to reinstall the dependencies of your applications. In other words, YunoHost's mechanism amounts to reinstalling and then reincorporating the data.
|
||||
|
||||
Making full system images can be a complementary or alternative way to backup your machine. The advantage is that your system can be restored to the exact state it was in at the time of the backup.
|
||||
|
||||
Depending on your type of installation, you can either create a snapshot or clone the storage medium by removing it from your server (turned off).

## Creating a snapshot
|
||||
|
||||
A snapshot allows you to freeze an image of the file system. Snapshots are very useful when doing an update or testing, because they allow you to easily go back in case of a glitch. On the other hand, apart from some very high availability clusters, snapshots do not really protect you against hardware failures or disasters (cf. OVH fire in Strasbourg in 2021).

Ideally, your hard disks should be fixed to avoid vibrations which can accelerate the wear of the equipment or even reduce its performance, especially if there is another disk next to it.

## Reduce swapiness for SD cards and SSDs

If you use a swap file with an SSD or SD card with too much swapiness, your storage media could give up the ghost prematurely due to too many writes.

There are also more advanced clusters that maximize fault tolerance (failure of 2 disks like RAID6) or storage (see RAID 5).

However, these disk clustering techniques should not be considered as backups. A RAID array should be considered as a single storage medium. Indeed, if this technique avoids having to reinstall in case of a probable disk crash, it is far from zero risk.

## PHP or HTML/JS apps
|
||||
|
||||
If your app is a PHP or HTML/JS app, you probably should use the `Custom Webapp`, also know as `my_webapp`, in order to configure nginx, php, mysql, YunoHost permission and backup for you.
|
||||
|
||||
## Other technologies
|
||||
|
||||
If you use some other technology, you should install it like on a classical Debian.
|
||||
|
||||
To expose the app on the web through nginx and be able to manage access permissions to the webapp, you could use the [`redirect` app](https://github.com/YunoHost-Apps/redirect_ynh/) to create a nginx reverse proxy on your local ip/port running the service.
|
||||
|
||||
!!! You should use the proxy mode of the redirect app and not HTTP redirections mode.
|
||||
|
||||
You probably should create custom backup and restore hooks to integrate your app to your YunoHost backup/restore process. See [Backup and restore hooks](/packaging_apps_hooks#backup-restore)
