Last week I was contacted by a customer who tried to install Microsoft Azure Backup Server (MABS) on an on-premise Windows Server 2016. However, when he started the installation he always received an error because a prerequisite was not installed, namely the Single Instance Store (SIS) component.
When opening the DpmSetup.log with PowerShell (as Administrator), you could see the following error:
Invoke-Item "C:\Program Files\Microsoft Azure Backup\DPM\DPMLogs\DpmSetup.log"
However, when you try to install this missing component through PowerShell it gives you an Error: 0x800f080c – Feature name SIS-Limited is unknown.
## Install Single Instance Store (SIS) component
Dism.exe /Online /Enable-Feature /FeatureName:SIS-Limited /quiet /norestart
The reason for this is that because from Windows Server 2016 the SIS-Limited component is replaced by Microsoft’s deduplication or data footprint reduction (DFR) technology, like you can read in the following article from MVP Greg Schulz: http://storageioblog.com/rip-windows-sis-single-instance-storage-or-at-least-in-server-2016/
Also, when you go to the Microsoft Azure Backup Server download page and you expand System Requirements you can see that Windows Server 2016 at the present time is not listed as a supported Operating System (OS) to deploy MABS, probably because it does not have this SIS component.
Currently you’re not able to use Windows Server 2016 as OS for you MABS server. Probably in the near future Microsoft will release a new version of MABS which will allow it, but until then you need to stick with Windows Server 2012 (R2) or Windows Server 2008 R2 to install your MABS on.
Hope this helps you with this error.
