Working with larger Lync deployments, I have run into this a few times where we need to force the Backup Service using Invoke-CsBackupServiceSync and we get the message “No Central Management services were found for the pool you specified to backup.”

The first time I saw it, it made me pause but I noticed something, it wasn’t an error. Errors always display in red. I went back to Technet and read about the cmdlet.

By default, the Invoke-CsBackupServiceSync command will attempt to synchronize three types of data:

  * UserServices.PresenceFocus
  * ConfServices.DataConf
  * CentralMgmt.CMSMaster

The issue comes up when you run Invoke-CsBackupServiceSync against a pool that is not hosting the CMS. The default attempts to synchronize CentralMgmt.CMSMaster.

If you don’t want to see the extra message telling you there is no CMS in the pool you are running against, then you can run Invoke-CsBackupServiceSync with the “-BackupModule” option and specify only the UserServices.PresenceFocus and ConfServices.DataConf. Otherwise, you can know that this message is normal and you can keep on with your tasks.
