yes, you can have MBR on that disk, but I do not know how can you use that. Probably it depend on the BIOS too.

Whilst I have never personally used it. You might want to look at Mondo Rescue

http://www.mondorescue.org/docs/mond....html#OVERVIEW

Quote:
Mondo Rescue backs up your file system to CD, tape, NFS (archives stored remotely) or ISO's (archives stored locally). Mondo uses afio as the backup engine; afio is a well-respected replacement for tar. In the event of catastrophic data loss, you may restore some or all of your system, even if your hard drives are now blank. Mondo Rescue can do a lot of other cool things:

- You can use Mondo to clone an installation of Linux. Just backup the crucial stuff and exclude /home, /var/log, etc.

- You can backup a non-RAID file system and restore it as RAID including the root partition (if your kernel supports that).

- You can backup a system running on one format and restore as another format.

- You can restructure your partitions, e.g. shrink/enlarge, reassign devices, add hard drives, etc, before you partition and format your drives. Mondo will restore your data and amend /etc/lilo.conf and /etc/fstab accordingly.

- You can backup Linux/Windows systems, including the boot sectors. Mondo will make everything right at restore-time. (However, do run "Scandisk" when you first boot into Windows, just in case.)

- You can use your Mondo backup CD to verify the integrity of your computer.

I was looking at the hard disk costs and I have found that hard disk costs are quite low these days (in other words not too expensive if you think how crucial my data are)

So the question then is
How about if I have an external hard disk of 3TB and having rsync running once per week? (like Sundays) and rsyncing my system to the external hard disk. If I am not wrong this will create on external hard disk a cloned version of my system. Would not that be true?

have you considered an image backup with dd ?
Code:
dd bs=8192 if=/dev/sdd | bzip2 > xbmc-01.05.2011.iso.bz2 # to create the image
bunzip2 -c ./xbmc-01.05.2011.iso.bz2 | dd bs=8192 of=/dev/sdd # to restore the image

If you have a large harddisk making backups with dd to external devices (unless you use USB 3.0) will become quite unhandy, since the large amount of data will be transferred very slowly.

dd is a valid point too. If I have the backup running every Sunday that would be ok I think.

I was also thinking of rsnapshot tool (or anything else that is based on rsync-philosophy), which provides also the notion of "cycles". I am not sure though where cycles could be useful and if I really need those.

Regards
Alex
