Impossible d'effectuer une sauvegarde complète de la batterie

Question

J'ai un serveur SharePoint 2013, contenant une application Web et trois collections de sites.

Je souhaite effectuer ma première sauvegarde complète de la batterie de serveurs. J'ai donc écrit la commande suivante dans SharePoint PowerShell :

Backup-SPFarm -Directory C:\Backup -BackupMethod full -BackupThreads 10 -Force

Après environ 1 heure, j'ai reçu l'exception suivante :

Voici les journaux associés, où il existe de nombreuses exceptions SQL :

La commande Backup-SPFarm doit utiliser un partage réseau où les comptes de service, les comptes de batterie et les comptes de service SQL Server ont un accès de contrôle total au partage.En effet, SharePoint utilise des commandes SQL pour exécuter des parties de la sauvegarde et celles-ci s'exécutent dans le contexte de SQL Server.

Plus d'information: Préparer la sauvegarde et la restauration des batteries de serveurs dans SharePoint 2013 Sauvegarder les applications de service dans SharePoint 2013 Rappel : utilisez un chemin UNC comme destination pour l'applet de commande Backup-SPFarm
