[SOLVED]Questions about making a system backup

Hi, yesterday I made a backup of my bunsenlabs system. That's what I did:

Previously, when I installed BL, I made two partitions of the same size. But they haven't the same size (/dev/sda1 [my sistem partition]is 14.90 Gb and /dev/sda6 [the backup partition] is 14.92 Gb). So, my first question is, why? is the MBR the difference of space?

Secondly, I made a backup usin dd:

dd if=/dev/sda1  of=/dev/sda6 bs=1M

i'm not sure, but I think than dd makes an exact copy of the partitions, so now I have a copy of /dev/sda1 on /dev/sda6.  But, what will happen if I try to restore the system? I'm not sure if it will be possible, at least usig dd, because the backup partition is larger than the original. Will I have problems with that? Is there any other way to restore that backup?

Thanks in advance

Óscar

I have never tried using dd to restore, because I use fsarchiver. It is easy, and an image can be restored to a different sized partition. You can run it from a live session, or from another bootable partition.
