The method I am going to show you involves using a piece of software called Clonezilla, which is opensource cloning software, so you will need to get your hands on it. You can download it from the Clonezilla website.

For the purpose of this tutorial I will be using Ubuntu 12.04 installed on a 500 Gb hard drive.  I will clone the installation using Clonezilla and then set up a RAID 1 array on two new 1 Tb hard drives.  Once the RAID 1 array has been set up I will then copy the Ubuntu image onto it.

Lets get started.  First thing to do is to BACKUP ALL YOUR DATA.  Even though you are effectively backing up your data when you image it I always recommend you backup your data using a different method just incase something happens.

Now onto imaging your system.  I have already written a tutorial which covers the required steps so rather than repeat myself please refer to the Clonezilla Tutorial for the method.

Once you have imaged your system connect your two new 1 Tb hard drives and disconnect the old 500 Gb one and again reboot the system using the Clonezilla Live CD.  Go through the menus the same as before until you get to the screenshot below.

This time instead of choosing Start_Clonezilla choose Enter_Shell.  Once at the shell we need to check our two new disks so type:

sudo fdisk -l

Write down the designations of the two disks (e.g /dev/sda) as we are going to need these later.

Now we need to create partitions and filesystems on the two disks and we do this by using fdisk.  The steps required to accomplish this are covered in How to format a hard drive on Ubuntu 12.04 using fdisk.

Now we need to install a package called mdadm which we shall use to set up the RAID 1 array so type:

sudo apt-get install mdadm

Once installed we can go about setting up the array.  In your terminal type the following:

sudo mdadm –create –verbose /dev/md0 –level=1 –raid-devices=2 /dev/sda /dev/sdb

NOTE: There are two dashes infront of create, verbose, level and raid

In the above command:

level=1 is the raid level (in this case Mirror)

raid-devices=2 is the number of hard disks in the array

/dev/sda and /dev/sdb are the disks to be used (obtained earlier using fdisk)

If successful then you should get mdadm: array /dev/md0 started

Now we just to check the array so in your terminal type:

mdadm –detail –scan (again using two dashes)

This command should return details of the array we have just set up.

All that is left to do is to exit the shell and resume Clonezilla so in your terminal type:

exit

which should return you to the screenshot we had earlier.  This time choose Start_Clonezilla.

Follow the wizard to install your saved image onto the new RAID 1 array.

We have all had this one.  Shall I go out and buy that new shiny ****** even though I don’t really need it?  This is a tough one but before you go and spend your hard earned think carefully about the following:

1. Do I really need it?  Can your existing equipment do what you are after?  Can you upgrade your existing system (e.g more RAM) so it provides the performance you are after?  Take the iPad2 as an example.  Is your original iPad really awful overnight?  Chances are the one you have can still provide the solution and performance you are after.

2. What happens to the old one you have?  In a world where people are beginning to think about the total life cycle of products what will you do with yours?  You could take it to the tip but why not instead give it to family or friends, kids, local charity shop or even make some money on ebay.  There will always be people on ebay who are not after the latest gadget.  If you don’t want to give it away why not use it for something else.  That old computer you have could be made into a firewall for your network or a NAS box for your backups.

3. Do you really have the money for it?  There is a reason that so many people are in a lot of debt.  People go out and buy things that they can’t afford – I myself am as guilty as the next person on this.  Think of the money you could save if you didn’t buy that new iPad2.  You could even take the kids on holidays too!!!!!
