You fine out that your hard drive failed. You're running some sort of critical system at work and you want to make sure that your down time is almost nothing. This is great when you have like critical machines. Pull that drive out and you take your clone, which is on the same type of hard drive, you stick it in, you close the back of your machine up. You can undo a little latch on the back of your machine. The primary use that people historically use clones for is for emergency swap out. This is why incremental backups, like Time Machine, are so much more superior. You have your backup from Tuesday and you're looking for file B but it's not there. The next day you get up and you look and you see files A and C and you realize, oh no file B is missing. You think everything is backed up and fine. You don't realize this as you go to sleep. So you no longer have file B either on your internal drive or on your clone. As a matter of fact it removes it there because it wants to make it an exact duplicate of the internal drive. You make sure that the external drive is an exact duplicate of your internal drive. Now you go and you clone your drive again. But you haven't yet realized that you've made this mistake. It's deleted but it's still backed up on your clone. Now the next day you start off and you have A, B, and C on your hard drive as well. You can go to sleep feeling secure that your files are backed up. You've got them on your internal drive and you have backups on your clone, on your external drive.
At the end of the day you've got a clone, an external drive, that also has A, B, and C. Maybe it's running automatically which would be great. So you're cloning your drive and you do your clone. These are important files and you want to make sure they're backed up. Let's say it's Monday and you create three files, A, B, and C. Now let me show you why cloning fails in a lot of cases. You just attach an external drive and Time Machine will automatically back your things up once you've set it up. You don't have to learn really much to use it. You don't have to have any special software.
The other reason is, of course, the Time Machine is just built in. It keeps this history there and it's so much more useful than a clone. So you can find deleted or modified files. You can go back in time to see what your hard drive looked like yesterday, last week, last month. You can go back in time which is why it's called Time Machine. If you delete the file it keeps around the old deleted version even as that version gets days, weeks, and months old where hasn't even been on your drive, it will still be there on the backup because it's doing it incrementally.
If you change a file it takes the changed file but it keeps the old file as well. So you create a new file it adds a new file.

It's storing every file you've got on your Mac now and then as you make changes it's recording those changes. The way it does this is it does this through incremental backups.
So the advantages of a backup over cloning are that it stores a copy of all of your files, even ones you've deleted.

It's not nearly as good as simply using the Time Machine software built into your Mac. You put this on an external hard drive and you've got a clone of what is on your Mac. Cloning is a method where you use a special piece of software to make an exact duplicate of your internal hard drive on your Mac. Video Transcript: I'm surprised that I hear from so many people that they still use cloning as a way to backup their hard drive.
