<div>Hi, I'm currently looking for ways to backup my disks. <br>
</div>
Live storage migration converted my disks from <br>
preallocated to thin provisioning. Preallocated disk <br>
backups are working from a simple dd from a snapshot, <br>
but the thin qcow2 disks are a problem. I seems it uses <br>
multiple logical volumes (3 in my case).</blockquote>
<div>For one snapshot? Are you sure?</div>
</div>
</blockquote>
Not anymore, i've deleted the host and its disks :(<br>

Also they <br>
are combined MUCH bigger than the preallocated:<br>
8GB raw vs thin: 31 GB - 1 snapshot.</blockquote>
<div>What version are you using?</div>
<div>And on what storage?</div>
</div>
</blockquote>
3.3 on iscsi. And I am talking about the LVM lv sizes. No idea how
much of that space the qcow actually occupies.<br>

<br>
So I have two questions:<br>
- how would you backup these thin disks?</blockquote>
<div>You could just copy all three of your volumes.</div>
<div>A more robust way, though, would probably be to export the
disk to an export domain.</div>
</div>
</blockquote>
The problem was, that i didn't know WHICH volumes to copy, but that
was probably due a wrong sql query.<br>
