<h1> Sauvegarde système de l'Orangepi sous debian/yunohost. </h1>

|
|
Sauvegarder le système de sa carte ARM OrangePi avec debian sur clé usb
|

</h2>

<hr />

|
|
|
<h3 id="le-probleme">Le problème</h3>
|
|
<p>Ou plutôt les problèmes, car il peut y en avoir plusieurs; par exemple le
|
|
système sur la carte ne boot plus. On a fait une bêtise, on la débranché car on
|
|
a voulu la déplacer ou le fil s'est débranché par accident, et aller cette fois
|
|
là c'est la galère. C'est généralement long et fastidieux de récupérer les
|
|
données sur sa carte SD ou autre, j'ai donc fait un script qui fait une
|
|
sauvegarde globale du système sur un disque ou une clé usb que l'on devra
|
|
autoriser auparavant, histoire que dès que l'on branche une clé usb, ça n'envoie
|
|
pas les données dessus. Il y a bien évidement des solutions de sauvegarde en
|
|
ligne mais ayant une connexion avec peu de débit, ça peut prendre beaucoup de
|
|
temps, la connexion peut couper et alors c'est des complications, pour moi ce n'était pas très adapté.</p>
|
|
<h3 id="le-principe">Le principe</h3>
|
|
<p>Le principe c'est que le script a deux fonctionnalitées
|
|
Une pour ajouter les supports de stockages où la sauvegarde sera envoyé. Le script formate la partition et il ajoute l'UUID à la liste des clés ou disques autorisé a recevoir les données. Pour l'utiliser on lancera la commande ./saveonmedia create
|
|
Une pour écouter avec udev les medias branchés et réaliser la sauvegarde quand elle reconnaît L'UUID d'un disque. On lancera la commande ./saveonmedia make
|
|
Pour la liste, un bête fichier texte suffit pour ajouter les supports de stockage lignes par lignes, on se basera sur les UUID des partitions sur le disque qui sont normalement identifier de manière unique. Pour réaliser la sauvegarde le script lancera un script bash qui est généralement plus pratique si l'on veut ajouter des taches à effectuer ou personnaliser le truc un peu comme on veut.</p>
