| It is also possible to utilize this function for creating absolute backup copies. xbian-config can directly create ''.img'' file you can later use to write back on your SD card. So restoring is as easy as installing XBian for the first time.

| + | ==== Procedure for Cubox-i ==== | ||
| + | 1. Unmount external drive and make filesystem: | ||
| + | <code> | ||
| + | sudo umount /dev/sda1 | ||
| + | sudo mkfs.btrfs -L xbian-usb /dev/sda1 | ||
| + | </code> | ||
| + | |||
| + | 2. Mount it and copy files from sd-card | ||
| + | <code> | ||
| + | sudo mount /dev/sda1 /mnt | ||
| + | sudo rsync -aAX /* /mnt/ --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found,/home/*/.gvfs} --progress | ||
| + | </code> | ||
| + | |||
| + | 3. Edit boot.scr.txt | ||
| + | <code> | ||
| + | sudo nano /boot/boot.scr.txt | ||
| + | </code> | ||
| + | |||
| + | change ''root=/dev/mmcblk0p2'' to ''root=/dev/sda1'' (or what your partition on the external drive is) | ||
| + | remove ''subvol=root/@,'' | ||
| + | |||
| + | |||
| + | and compile boot.scr with (make backups of both files beforehand - just in case): | ||
| + | <code> | ||
| + | cd /boot; sudo ./mks | ||
| + | </code> | ||
| + | |||
| + | Reboot | ||
| + | |||
| + | That's all! | ||
| + | |||
| + | **To use sub volumes again:** (Important for filesystem snapshots) | ||
| + | <code> | ||
| + | sudo -i | ||
| + | cd / | ||
| + | btrfs sub create ROOT | ||
| + | btrfs sub snap / ROOT/@ | ||
| + | </code> | ||
| + | |||
| + | and then re add the previous deleted text at the same position: | ||
| + | <code> | ||
| + | sudo nano /boot/boot.scr.txt | ||
| + | </code> | ||
| + | ''subvol=ROOT/@,'' | ||
| + | and compile it again with: | ||
| + | <code> | ||
| + | cd /boot; sudo ./mks | ||
| + | </code> | ||
| + | |||
| + | (It's important that ROOT is written the same way as created, in this case in capital letters!) | ||

| + | |||
| + | ==== Troubleshooting ==== | ||
| + | Some external USB drives such as Seagate Expansion take longer than 10 seconds to spin up on boot, resulting in xbian not identifying the xbian-copy partition in time and results in recovery mode on start up. | ||
| + | |||
| + | It is necessary to add appropriate delay in the initramfs script between device initialization and root mounting to resolve this issue. | ||
| + | |||
| + | <code> | ||
| + | xbian@xbian ~ $ sudo nano /etc/xbian-initramfs/init | ||
| + | </code> | ||
| + | |||
| + | Add ''sleep 10'' on a new line between ''up "after modprobe"'' and ''INITIALBOOT="0"'' | ||
| + | |||
| + | <code> | ||
| + | ... | ||
| + | up "after modprobe" | ||
| + | |||
| + | sleep 10 | ||
| + | |||
| + | INITIALBOOT="0" | ||
| + | ... | ||
| + | </code> | ||
| + | |||
| + | Adjust the delay from 10 to the appropriate amount needed for your external drive. | ||
| + | |||
| + | Now, update the initramfs image: | ||
| + | |||
| + | <code> | ||
| + | xbian@xbian ~ $ sudo xbian-update-initramfs | ||
| + | </code> | ||
| + | |||
| + | The system should now boot from external USB drive properly. The only downside is a few additional seconds wait time during boot up. | ||
