Windows Azure Backup - Fails on Drive C: (OS Drive)
<p>I am using the following:</p>

<ul>
<li>Windows Server 2008</li>
<li>Windows Azure Backup (latest version from azure site)</li>
</ul>

<p>I have two drives I am backing up:</p>

<ul>
<li>C: (OS Drive)</li>
<li>G: (Attached Drive 1)</li>
</ul>

<p>The backups complete fine for Drive G but repeatedly fail for the primary operating system drive C: with the following error message:</p>

<p>An unexpected error occured during the operation. Retry the operation. (0x07EF9).</p>

<p>I have tried the following:</p>

<ul>
<li>Re-install Azure Backup &amp; Re-register server</li>
<li>Create a new Vault and try then </li>
<li>Defragment hard drive.</li>
</ul>

<p>Please advise. Thank you.</p>
