Backups

Depending on how critical your files are, you need to consider which backup strategy is most appropriate and easiest for you.

  • No backup method will work unless you actually use it!
  • Always have two or more backups.
  • Make sure one of these is a mirrored backup of your entire computer. If your computer fails, that can be used to restore your information to another hard drive or computer.
    For example, Apple Time Machine provides a full restoration of your computer as well as work with individual data files. So if your laptop hard drive died on a Friday and you had a paper due Monday, a mirrored backup would give you access to all your files on another computer.

The following table summarizes the advantages and disadvantages of various backup options.
