Les scripts de sauvegarde et recouvrement pour Exchange

Avec l’arrivée de solutions en ligne, je me suis penché sur les problématiques que ce type d’environnement pouvait poser en termes de disponibilité pour le contenu de vos boîtes aux lettres.

Après la préparation du plan de recouvrement dont nous avons parlé la semaine dernière, nous allons voir ici les scripts à utiliser.

Le script suivant permet de sauvegarder une boîte aux lettres ou l’ensemble des boîtes aux lettres d’une entreprise. Il vous suffit de recopier les instructions suivantes dans un fichier texte que vous renommerez Backup-MSOnlineUserMailbox.ps1. Procédez de même pour le script de restauration.
