Exchange Circular Logging in SBS 2008
While studying for exam 70-653 (SBS 2008, Configuring) I got aware of the fact that Circular Logging in Exchange 2007 are enabled by default in Small Business Server 2008. When the “Configure server backup”-wizard are run, Circular Logging are automatically disabled afterwards.
For those using a 3rd party backup software this means that Circular Logging must be manually disabled. This is a real gotcha which should be stated clearer for SBS admins in my opinion.
Like I`ve configured in one scenario, backup are set up on a separate server using 3rd party backup software. Still the “Windows SBS Console” shows a warning stating that “Backup is not configured”. I contacted Microsoft support asking if it is possible to disable this warning, which it turned out to not be. I think there should be an option for choosing that the integrated Windows Server backup (which can`t backup to tape drives like NTBackup did) will not be used in the “Configure server backup”-wizard, in addition to giving the option whether to disable Circular Logging.
Hopefully this will be implemented in a future SBS Service Pack
