Backup Wheezy Raspbian operating system with piCore

This is must have method how to backup you raspian operating system raspberry if the pi is your only computing device. As a part of this cloning method you are recommended to keep the default size of partition table like original. So you do not expand your raspbian!

You need wireless keyboard with mouse which works with only one USB receiver. Logitech wireless keyboard MK220 is pretty nice choice:

You need at least 64Mb (not GB) SD card where the TinyCore will be placed.

One additional fat32 pre-formated USB drive. Of course ext2, ext3 and ext4 are supported.
If you choose larger than 32gb then you can forget to use fat32 file system.

And the last thing is wheezy raspbian operating system which has not been extended to all SD card.

Use https://sourceforge.net/projects/win32diskimager/files/latest/download to push piCore image to the small SD card

Now boot the piCore system.

1) open terminal
2) open mount tool
3) click sda1 to mount usb storage:

4) swap you piCore SD card to raspbian card. The name of this procedure calls brutal hot swap :D

5) launch

sudo dd if=/dev/mmcblk0 of=/mnt/sda1/raspbian-2014-07-27.img bs=1M count=2825

power down the system:

sudo poweroff
