<p class="MsoNormal">Hello<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I have a VM with Windows 2012 running nicely in PVE 3.2.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">This VM has a 300 GB disk size that was re-partition with 5 or 6 different parts, in order to allocate different databases...<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">The issue is that the backup task takes 6 hours to generate a lzo file with 13 GB size!<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">However, I have another VM, which is Windows 2008 with disk 120 GB size.<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">The backup makes 74 GB file of size, and takes approximately 30 minutes!!!<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">I can't see why the first task took so long time to finish!!!<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">Can anybody assist me??<u></u><u></u></p>
