It is, roughly speaking, a tar archive with special checksum files to ensure pwds are correct. I always to these backups by hand, to keep myself trained. My method "sous-entend" that you "safe backup": in your life system generate a container file (truncate -s 200G /externalstorage/backup.luks), then losetup: (first losetup -f to get a free slot, then bind it with losetup /dev/loopX /externalstorage/backup.luks ), and cryptsetup luksFormat /dev/loopX ;cryptsetup luksOpen /dev/loopX BACKUP; mkfs.ext2 /dev/mapper/BACKUP ; mount /dev/mapper/BACKUP /somemountpoint For rsync'ing back inside qubes from subfolders you - attach usb to dispVM1 (widget) - lopsetup the container - attach container mapper to dispVM2 (widget) - there start same procedure as above at "luksOpen" step and then attach the full decrypted backup to each VM with the widget, and rsync back the correct subfolder in your home. You can use --exclude to avoid "dot"-files ... best, Bernhard -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

From a newly installed Qubes on a different disk, I can mount my crashed disk, decrypt it and access all my Qubes, DOM0... I see two options to recover my environment (and would prefer the first): 1- Fix my Dom0 environment on my crashed hard drive (I have another drive with a newly installed Qubes 4.0-rc3) 2- Save my qubes from my crashed disk, and restore them on my new 4.0-rc3 install. Any advise to perform a rescue for option 1 or 2 is welcomed ! 1) try to boot from a life system. Mount /boot and, in case of UEFI, have a look in efi/qubes/xen.cfg or efi/BOOT/xen.cfg you should be able to select a older kernel. Maybe that allows to reboot. 2) emergency backup is a good idea in any case. Open the encrypted volume (using luks)then runvgchange -ayto activate all logical volumes.

Re: [qubes-users] Dom0 Kernel panic when using iGPU
> Have you tried taking out iommu=no-igfx (in both places) and/or i915.alpha_support=1? I have just tried this. No change. Using the serial console still results in the same kernel panic. Without the serial console, there is no output from Dom0. I also was recommend pci=nocrs in the console output while testing. Same result for this. Of interest, while testing the above I accidentally left the Nvidia GPU active. I received exactly the same kernel panic in serial console with the Nvidia GPU as I usually do with the iGPU. It may be that the error I am looking at is a result of the console, and the real error is something else.
