You can use rsync and a perl script to keep rotating snapshots with minimal duplication.
You can use rsync for the initial copy as well.
I would also suggest using a USB external drive. That way you will not have both drives corrupted by a bad controller, or simultaneously trashed by a power surge or motherboard fault.
This is what I do, and I also do a network backup. I use the grsync GUI front end for rsync for both.

Thanks for the reply!
Would I need to keep all those partitions in sync? Or just perhaps /home, /usr, /var ?
Thanks

Depends on your requirements.
For desktop use I only keep /home in sync. For a server you might want to keep other directories in sync as well. Where is your (valuable) data? Do you have time to do a re-install to recover, or do you need to be able to swap drives and keep going?
I only do this for desktop use so I cannot confirm how well it works if your requirements are more extensive,

Its actually for a server, I'd like to be able to simply replace the drive and continue on.

It should work AFAIK, but you can probably find articles on this on the net, and relevant threads on the rsync list archice.

On my server I have two internal SATA drives, the first is partitioned and takes the operating system and primary copy of my work which is mount as work. I then formatted the second drive and mounted it as backup. Crontab then runs a backup script each night to ensure that I have a backup for everyday of the week therefore I have 7 days to realise a mistake.
In addition, I also have a LACIE USB hard-drive which acts as a removable copy which I can take off-site. The backup script e-mails me each morning to tell me if the backups were successful so that I can address any issues, the most common is that the LACIE has been powered down for one reason or another.
Although there is no way to remain 100% covered for everything I find the best policy is to change the drives in my server every 3 years or if any signs of bad sectors start appearing.

@Jamier101, do you use SMART disk monitoring? I just started when I realised that everything is pre-installed or in the repos - even nice GUIs to do it with on desktops.
