every week we perform a full backup of our SharePoint environment using the backup-spfarm command:

backup-spfarm -directory $directory -backupmethod full -Verbose

and every week, after the backup is performed, the User Profile Synchronization Service goes down. It also takes down the Forefront Identity Manager Service and the Forefront Identity Manager Synchronization Service.

Is there something that can be done to prevent the UPSS service from going down?

  • make sure the farm account in local administrator group Mar 29, 2017 at 16:52

1 Answer 1


This is expected behavior. When a full backup is run (or a backup of the UPSA object), the UPSS is deprovisioned (stopped). If the Farm Administrator is a Local Administrator on the server where the UPSS is running, it should start itself when the backup process has completed.

The alternative is to switch to SQL Server-based backups.

One other thing, the reason the account must be a Local Administrator is simply that the code to start the UPSS attempts to make a call to the local machine's SAM (Security Account Manager database) which can only be performed by Local Administrators.

  • Thanks, will add the accounts as local admins and see what happens after the backups are run this weekend. Mar 29, 2017 at 20:59
  • Keep in mind that best practice dictates that the farm account is not a member of the Local Admins group.

  • This is a requirement for the UPSS. And the Admin token sticks around until you restart services, therefor you cannot remove it from the Local Admins group.

  • I verified that the farm account is a member of the local admin group....it is still not restarting the service. Any thoughts on what else it could be? Apr 3, 2017 at 21:38
