Bonjour,

J'ai forké votre script borg pour y intégrer le chiffrement simple via passphrase (repokey) ainsi qu'une limitation de bande passante : https://gist.github.com/leoberry/b6431b0fdb8f04693977d86dbfe8ca77

Vue qu'il n'est pas possible d'effectuer un pool-request sur un gist je vous laisse donc ce commentaire.

Bien cordialement,
Léo Berry
