Every night we run a farm backup via PowerShell Script, but after that the User Profile Service is unprovisioned. I've found this article:
Using the SharePoint Backup (Backup-SPFarm or via Central Administration) purposely unprovisions the User Profile Service during the backup of the User Profile Service Application. It also automatically re-provisions itself once the backup of the User Profile Service Application is completed. Unfortunately, this means that the Farm Administrator account must be a Local Administrator on the server where the User Profile Synchronization Service is running. This is counter to the documentation on TechNet regarding least privilege. If the Farm Administrator account does not remain as a Local Administrator, the provisioning will fail.
Does anyone have a solution for this problem??
Thanks and Regards
