I have a Dell Venue Pro 11 (model 5130 tablet running 8.1 32 bit fully patched) which I am trying to back up using Windows Home Server 2011.  I can start the backup but it fails repeatedly. 

The server reports "Backup did not complete because a problem interrupted the connection to the server"

The event log on the tablet reports "Reason: ClientVSSProblem, SystemString[]

Event Id 514, Qualifiers 53247, Level 2 Task 2, Keywords 0x80000000000000

The Tablet and the Server are in the same workgroup, the tablet is setup to permit access by everyone (with full control) in the workgroup.

When setting up the backup on the server, the C drive is recognized, but the D (microsd card) is not recognized by the server

The backup starts, reports 1%, then fails.

The Tablet is running plugged in with the power plan set to never turn off when plugged in.

I have a desktop running 8.1 which the server backs up daily, so I doubt that the problem lies with the server software.

Any ideas on how to correct this problem so that I can back up the Tablet?
