Backup compression is done on a block level (there is no
filesystem knowledge), so you can have "dirty" blocks in the
virtual device that don't compress well, although you guest
filesystem knows they're free.<br>

<br>
I have one VM win2012r2 with two virtio qcow2 disks .<br>
1st one is 100G big with 20G data on it.<br>
<br>
I'm backing only this partition up , 2nd one has "no-backup"
flag, <br>
and backup archive turnes out to be 72G big .<br>
<br>
How is that possible since I have "only" 20G of data ?<br>
<br>
Thank you very much in advance and <br>
<br>
