@Karen

there is tool called btrfs-auto-snapshot available with package 'xbian-package-config-shell'. it allows you to create .img of size you specify. xbian-config -> xbian copier is using it for backups / cloning / usb installation creation. additional options (which it offers via command line) are not yet available in GUI, but are available if you run it via ssh:

Code:

sudo -i
btrfs-auto-snapshot xbiancopy --img --size 2G /dev/root /path/to/my/file.img

this will create /dev/root /path/to/my/file.img as Image suitable for flashing directly to SD card including /boot partition and modifying /boot/cmdline.txt accordingly so you don't have to edit anything after flashing. just put it RPI and you backup copy should boot.

for size 'human readable' numbers are accepted with suffixes as M, G, K etc (1500M, 1G, 2000000K … )

for your question if updates will rewrite your xbmc (compiled by you) - by default yes, of course. if you update xbian-package-xbmc and your compiled version is using the same paths (/usr/local/lib/xbmc and /usr/local/share/xbmc). there are more ways how to avoid this, but the most standard would be to mark xbian-package-xbmc as hold with apt-mark

Code:

sudo -i
apt-mark hold xbian-package-xbmc

if you are using XBian's auto update feature, create file /etc/apt/apt.conf.d/99unattended-upgrades file with this content:

Code:

Unattended-Upgrade::Package-Blacklist {
//      "xbian-package-kernel";
//      "xbian-update";
        "xbian-package-xbmc";
};

you can add/remove/uncomment according to your needs.

btw: was something missing / not working with the XBian's provided XBMC Gotham package for you? or what was the reason to use custom compiled version?
