Info on how to back up my new debian sarge stable system

Hi all,

So, I've finally got a working debian stable sarge system up and running. This was my first time using linux, so far I am quite impressed, for some reason I was under the impression that linux would be MUCH different than I am used to. Anyway, now that I have everything setup what I want to know is can I create a backup so that when I start playing with the system (upgrading the kernel, etc) and I inevitably break things because I don't know what I'm doing yet, I can fall back to my current setup with out reinstalling from the debian Cd's. What I'm finding is the hardest thing is that things which I figured out how to do in windows years ago I don't know how to do in debian, for example it took me forever to set a static IP for port forwarding and to configure the samba to see the shared files on my winxp machine. It is fun though, doing a lot of learning. If you guys can help me out with this backup thing I'm sure it will save me tons of time.

Info on how to back up my new debian sarge stable system


For a full backup of the system, I suggest :
- boot with a live cd live knoppix
- have a HD with free space and with ext3 filesystem
- backup the MBR of the master drive using 'sfdisk'
% sfdisk -d /dev/hda > hda.out (this save the hda MBR)
% sfdisk /dev/hda < hda.out (this replace the hda MBR if you need to restore the partition table)
- mount the partition and create a tar archive of the mounted partitions
exemple with 2 partitions ext3 (dev/hda1 and /dev/hda2) and 1 swap (/dev/hda3)
- no need to backup the swap partition
- mount -r /dev/hda1 /mnt/hda1
- cd /my_backup_place
- tar cvfzps hda1_backup.tar.gz /mnt/hda1
- mount -r /dev/hda1 /mnt/hda2
- tar cvfzps hda2_backup.tar.gz /mnt/hda2

That's the way I work, it's not always the easiest but it's the way I do.
