Windows 10 backup to Windows Server Essentials 2012 R2

Hi,

I have installed the connector (Windows10.0-KB2790621-x64.msu) and I have used the same procedure as before to skip joining domain and also to skip auto dns server detection on the Windows 10 client.

Something is wrong because I am unable to backup the Windows client. The backup fails almost immediately.

The logs on the client, we can find the lines below (excerpt from SharedServiceHost-ClientMgmtServiceConfig.log) which makes me think at first that it was a problem of  certificate and trust between both computers.

However I made further tests. The problem seems to come from the partition on which Windows 10 is installed. Here is the setup. There are 2 SSDs in the computer. The first one had Windows 8.1 and I installed Windows 10 Education on the second one. The first one is partitionned with :

DISKPART> list partition

  N partition   Type              Taille   Dcalage
  -------------  ----------------  -------  --------
  Partition 1    Rcupration       300 M   1024 K
  Partition 2    Systme            100 M    301 M
  Partition 3    Rserv            128 M    401 M
  Partition 4    Principale         237 G    529 M

(Partition 4 here is mounted as D: drive on Windows 10)

and the second one with :

DISKPART> select disk 1 Le disque 1 est maintenant le disque slectionn. DISKPART> list partition

  N partition   Type              Taille   Dcalage
  -------------  ----------------  -------  --------
  Partition 1    Principale         465 G   1024 K

Partition 1 here is C: drive.

I can let Windows Server 2012 Essentials R2 backup D: drive, but it fails to backup C: drive.

I must add that I have run 'chkdsk /f' several times on all partitions and there are no errors.

Given the error message below I can see 2 possible reasons :

- ESP partition is too small for the C: drive which is twice as large as the previous D: drive

- C: drive has shadowstorage onto itself as reported by vssadmin and that is not handled properly :

C:\ProgramData\Microsoft\Windows Server\Logs>vssadmin list shadowstorage
vssadmin 1.1 - Outil ligne de commande dadministration du service de clich instantan de volume

(Sorry, messages are in French, hope it is readable anyway)

Any idea of what is going wrong by me and how to solve it ?

Thanks in advance and best regards,

Fabrice

Hi,

According to your description, my understanding is that WS Essentials 2012 R2 failed to backup Windows 10(this computer also has Windows 8.1 installed).

In general, when deploying Windows client computers in a Windows Server 2012/2012 R2 Essentials network, joining the Windows Server 2012/2012 R2 Essentials domain is mandatory. If the client computer is already joined to another domain, you are required to manually leave the existing domain. 

However, if you skip the domain join process(steps mentioned in below link), some features are limited, such as domain credentials, Group Policy, VPN:
https://technet.microsoft.com/en-us/library/jj713510.aspx?f=255&MSPPError=-2147217396#BKMK_10

According to the log, it failed to back up C drive which has Windows 8.1 installed, and logged with Build chain failed for the following certificate and EspCaptureFailed. You may try to check the EspCapture.log and confirm that if any available information has been logged. Detailed steps you may reference:
