Error backing up item exit status 3 Couldn't create virtual device set : Erreur inconnue 0x80770005

This error might be caused if the user account running the backup is not included in the Security Setting for the "Create global objects" in the "User Rights Assignment" of the Local Security Policy.

In Control Panel, under Administrative Tools, open the Local Security Policy editor and expand ‘Local Polices’ -> 'User Rights Assignment' locate 'Create global objects'. Ensure that the group and or user performing the backup is within the Security Setting for the 'Create global objects' field. Add the user/group to this policy if they are not a member.

Vous pouvez également vouloir changer le service de sauvegarde pour qu'il s'exécute en tant qu'utilisateur privilégié. Ouvrez Run -> services.msc, localisez eazyBackup delegate et elevator services. Arrêtez les deux services, changez l'utilisateur de connexion pour votre compte Administrateur local ou un compte avec des privilèges suffisants et redémarrez les deux services.

Ensure the account running the backup service (eazyBackup delegate and elevator service) also belongs to the 'Create global objects listed above.
