Peter Cohen and Lory Gil, writing for iMore:

If you’re using any one, individual technique to make sure your Mac is backed up, you may be wondering why you have to combine strategies at all. The main reason is redundancy: You don’t want a single point of failure in the system to keep you from gaining access to the files that you need.

My current backup system includes all of my Macs running Time Machine pointed at our Time Capsule and myself occasionally making clones with SuperDuper. I know it’s not as comprehensive as it should be. Here are the two main problems:

• I don’t have an offsite backup.
• There’s no system in place for regular SuperDuper clones — I do them when I think about it, which is less frequently than I should.

What I hope to do in the future is sign up for BackBlaze, which will give me an offsite solution, and setup a reminder system for cloning.
