What does the status reported by Get-CsBackupServiceStatus mean?

  • Artikel

The Lync Server Backup Service is a new service in Lync 2013 Server used to support disaster recovery (https://technet.microsoft.com/en-us/library/jj205293(v=ocs.15).aspx.

The Lync Server Backup Service supports two categories of data (UserData and CMS), which it will copy between paired pools to keep them synchronized. The implementation use three modules: UserServices.PresenceFocus, ConfServices.DataConf and CentralMgmt.CMSMaster. The modules can operate both in Import or Export mode. The Lync Server Backup Service collects the changes into batches before copying it to the paired pool. The Backup Service is only active on one of the front ends in a pool.

In order to see detailed status from the Lync Server Backup Service use the following cmdlets:

  • $BackupStatus = Get-CsBackupServiceStatus –PoolFqdn <pool fqdn>
  • $BackupStatus.BackupModules

This will produce output like below:

Identity ExportStatus ImportStatus

-------- ------------ ------------

UserServices.PresenceFocus FinalState NormalState

ConfServices.DataConf FinalState NormalState

CentralMgmt.CMSMaster NotInitialized NormalState

 

The table below lists the meaning of Export and Import Status. Please note that the output above is for a pool, which is not the active CMS master. That is why the ExportStatus for CentralMgmt.CMSMaster is NotInitialized.

Backup Type

Status

Explanation

Export

FinalState

Backup module has no more changes to back up, and all changes have been imported to backup pool

Export

SteadyState

Backup module is able to back up all available changes in one batch. This means that generated changes can be backed up without a backlog

Export

NonSteadyState

This state means that generated changes at this point is beyond the capacity of backup service and backlog will be generated

Export

NotInitialized

The status is not yet initialized. Usually it is the state before backup module starts the first export operation

Export

ErrorState

Backup module is failed to back up new changes so the exact status (e.g. has change or not, etc.) is unknown due to the failure

Import

NormalState

Import operation is working well

Import

ErrorState

Backup service is failed to import new changes

    So for the CentralMgmt.CMSMaster there's no FinalState status? Jens>For the pool with the active CMS the ExportStatus will be FinalState and ImportStatus will be NotInitialized. For the passive CMS the ExportStatus will be NotInitialized and the ImportStatus will be NormalState.
