Hi,
I recently rebuilt my WHS 2011 with Server 2012 Essentials but am experiencing issues with backups when the Client computer backups folder is on a Storage pool.
If the Client backups folder is on the system drive or an individual hard drive it works fine but as soon as I move the folder to a storage pool it fails after around 1-2%.
I see the following errors:
On the Client (Windows8) -
Event ID 8194 - Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. hr = 0x80070005, Access is denied.
. This is often caused by incorrect security settings in either the writer or requestor process.
Operation:
Gathering Writer Data

I've tried it with a storage pool of 3 disks with parity, and 2 disks mirrored, both scenarios fail. I've tried with ReFS as well as NTFS for the file systems.
I can replicate easily: move the Client Backups folder to C: or other individual drive and it works, move the folder to use a storage pool and it fails every time. I've tried rebuilding the server many time with the same result. MyWindows 7 client doesn't back up either. Has anyone else experienced this or have any ideas how to resolve this?
Thanks,
Paul
