3. Back up methods
3.1 Hard drives
A popular and easy method to back-up files is to use external hard drives. These are fairly affordable now and enable terabytes of data to be stored in the same place. This is useful for full back-up of data. If you choose this method make sure that you back up regularly and that the drive has enough spare memory for the increase in files that is likely to occur throughout the research process.
One thing to remember about external hard drives is that they can fail suddenly and unexpectedly. NEVER rely solely on external hard drives to store files as they will – at some point – let you down. They are, however good places for back-ups when you have at least one other device containing the same files.
