How to extract a backup from dom0

[Franz]

After the recent update I lost all communications out of dom0, no network as already described here https://groups.google.com/forum/#!topic/qubes-users/unDqbBa_k_Y

Also  USB sticks do not mount anymore even after deleting all assignments of 00:1a.0  and 00:1d.00  

But dom0 still works, so made a backup of  all VMs. But how to take the backup out of dom0?

I imagine can boot with a live Qubes or live linux distribution and from there try to find my backup somewhere. But where? Also everything is encrypted, so how may I decrypt it?

Well, it seems complicated but perhaps there is a tutorial or something.

Any idea?

Boot a live-linux with built-in LUKS support. Tails for example
(activate root access after boot).
Then "break in" by hand following standard tutorials "how to mount a
luks drive", and copy all
to your usb disc. consider generatinga huge sparse-file, say, BACKUP.enc
then loop-it:
losetup -f % findes out a free slot
losetup /dev/loopxxx BACKUP.enc
Now /dev/loopxxx is a device that can by crypt-setuped by luks in a
standard tutorial way. Mount it, and move your data in.

Do you have Qubes installer anywhere? If so, boot it, choose you want to repair the system. You will be prompted for disk encryption password(s). It will try to autodetect where your broken installation lies and mount it under AFAIR /mnt/sysimage. Then, you can access it or (if you want) chroot to it.

With the rescue mode, you probably won't be able to connect to network, but USB should work.
