Well I'm trying to prove the Idea first in virtual environment, I don't want to screw up actually backed up data on real external disk and also it would take 2 hours each try on real drives to copy 100GB.
So I installed 2 different small linux distributions on 2 virtual disks in virtual machine simulating the stuff with much less data, so I have a sandbox to play with.

I want the external disk to be bootable. So I can boot directly from it and it will handle copying data from live OS disk to external disk itself.
I prepared external disk with small partition in the end of disk and made disk bootable from it. Linux starts up and runs shell script with steps I described.
I'm copying the data from lsource disk to external disk from position 0 which overwrites MBR on external disk with MBR of source disk, so I back up MBR of external and then restore it.
I coudl possibly do copy of data from position 513 which possible is the same thing as backing up and restoring later isn't it?

I just want to copy data from source disk to external but keeping external in its actual state, bootable and booting from partition at the end of the disk.
What I assumed was that if I keep external disk MBR including partition table created for one partition at the end, it would not matter on other data copied to the disk after MBR and not touching partition at the end of the disk.
I'm I completely wrong here?

FDISK(8)						      System Manager's Manual							  FDISK(8)

NAME
fdisk - partition a hard disk [IBM] SYNOPSIS
fdisk [-hm] [-sn] [file] OPTIONS
-h Number of disk heads is m -s Number of sectors per track is n EXAMPLES
fdisk /dev/hd0 # Examine disk partitions fdisk -h9 /dev/hd0 # Examine disk with 9 heads DESCRIPTION
When fdisk starts up, it reads in the partition table and displays it. It then presents a menu to allow the user to modify partitions, store the partition table on a file, or load it from a file. Partitions can be marked as MINIX, DOS or other, as well as active or not. Using fdisk is self-explanatory. However, be aware that repartitioning a disk will cause information on it to be lost. Rebooting the sys- tem immediately is mandatory after changing partition sizes and parameters. MINIX, XENIX, PC-IX, and MS-DOS all have different partition numbering schemes. Thus when using multiple systems on the same disk, be careful. Note that MINIX, unlike MS-DOS , cannot access the last sector in a partition with an odd number of sectors. The reason that odd partition sizes do not cause a problem with MS-DOS is that MS-DOS allocates disk space in units of 512-byte sectors, whereas MINIX uses 1K blocks. Fdisk has a variety of other features that can be seen by typing h. Fdisk normally knows the geometry of the device by asking the driver. You can use the -h and -s options to override the numbers found. SEE ALSO
