Backups and Transfers
When you have finished your project you should tidy this up and back it up to make way for the next project.
A golden rule of computing says that if it only exists on one hard disk, it probably doesn’t exist at all. All it takes is a few errors on the hard drive to make the disk directory unreadable, so that you can’t find your files. Software such as Disk Warrior can help prevent such catastrophes, but disasters can still happen. As I am writing this chapter, I am having disk directory problems with three of my hard drives, and one appears to have completely failed. And these drives are all less than 18 months old and have been regularly maintained. One of the drives was purchased just a week ago!
