As you can see, I'm fast running out of space. I'm looking to upgrade my capacity in the most effective way possible, and I'm wondering what I can do with this setup and an extra £100-150. I want some sort of backup* option, as obviously I'd hate to lose all that data to some hard disk fault or other fkup. I realise a RAID5 setup is out of my price range, but are there any other ways to increase capacity and provide some sort of stable backup* in that price range?
