Hi, </p>
<p>First of all, proxmox has nothing to do with this, because this is a linux/qemu feature and not the distribution.</p>
<p>My question: you created 13 snapshot on windows and the differences between them have zero space?</p>
<p>Normally windows change the data on the disk a lot of times per days.</p>
<p>For example:</p>
<ul>
<li>logs,</li>
<li>active data of user apps,</li>
<li>virtual memory (this could be huge!)</li>
</ul>
<p>So, my opinion, all changes of your 13 snapshot could be easily 160GB and that's all.</p>
<p>When you converted your qcow2 image to raw, you only got your recent data and drop all snapshots.</p>
<p>So, test the theory:</p>
<ul>
<li>create backup,</li>
<li>delete each snapshot one by one, check the filesize</li>
</ul>
<p>My general advice:</p>
<ul>
<li>before you start using a framework like proxmox, you should learn some basics about the used techniques,</li>
<li>you should get experiences with windows to see for example, how often it touch the disk under your workload,</li>
<li>even it seems very easy to use proxmox and we all like it, that does not mean, one will be safe running such a system without knowledge</li>
</ul>
<p>I guess it is a test machine and you are experimenting with proxmox. If it is a production system, cross fingers. :)</p>
<p>Anyway, personally I changed to ZFS on linux local filesystem, instead of the default or hardware raid or other software raid solutions. My benefits:</p>
<ul>
<li>on the fly compression</li>
<li>unlimited snapshots for all kind of VMs</li>
<li>zero-time backup (with snapshot - 0 time instead of 8-10 hours heavy workload and it does not need a lot of free space)</li>
<li>off-site backup is easy</li>
</ul>
<p>I was sick about the necessary backup time and workload, wasted space, slow remote backup etc.</p>
<p>Bye,</p>
<p>István</p>
<p> </p>

Maybe you store snapshots?<br>
