HI All,

Newbie here and new to using Sysinternals Disk2vhd to do backups. I have a the following server:

Windows 2008 R2 Server (fully patched)
Running MS SQL Server
Disk C - 930GB (89GB Used) - Creates a 63GB VHDX File
Disk D - 930GB (114GB Used)  - Creates a 77GB VHDX File
Disk E - 930GB (63GB Used)  - Creates a 70GB VHDX File
2 6 Core Xeon Processors (giving 24 Logical)
16 GB Physical Memory
Disk2vhd - Version 2.01 (dated 20/01/2014)

I use Disk2vhd to backup to a network location using a the following command:

c:\backup\disk2vhd * \\\data\the_server\the_server.vhdx

Now to the issue at hand. The first 2 hard drives backup fine (Disk C & Disk D), but the third disk (Disk E) only backs up 11.2GB and then the application hangs. Not sure if it being the main MSSQL Database storage drive is relevant. I can then backup the third disk drive fine using the following: 

c:\backup\disk2vhd E: \\\data\the_server\the_server-2.vhdx

Right royal pain in the backside having to manually do it everyday it fails. I did see the following in the eventvwr which I had fixed, but it is still failing on that disk drive (and I don't believe it is related to the issue):

Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface.  hr = 0x80070005, Access is denied.

The thing that is really annoying is that it will go sometimes for for a few days working fine, then it will error for a week or a day, so it doesn't make sense to me why. If anyone knows why this would happen, would appreciate information on how to over come it and fix it.

I am am going to try the following, but not the preferred method for the work around:

c:\backup\disk2vhd C: \\\data\the_server\the_server-0.vhdx
c:\backup\disk2vhd D: \\\data\the_server\the_server-1.vhdx
c:\backup\disk2vhd E: \\\data\the_server\the_server-2.vhdx

I have another 3 servers that I do the backups this way and do not have an issue with them.

Much appreciate any help.
