[PROBLEM] xbiancopy fails after upgrading

[jyviko]

Hi all,

First of all I would like to thank all the contributors for building this amazing package.

Problem description:
I used to utilize the xbian-copier from xbian-config to backup my xbian to an .img file, but after upgrading I am running into an error. I have tried also using

Terminal

btrfs-auto-snapshot xbiancopy --img /dev/root /media/backup/file.img

and got the same. I get the error shown in the attached picture     , the process ends after a few seconds and a file of zeros bytes is created in the destination folder.

Any thoughts? Is my filesystem corrupted?

Best,
Iraklis
