And yet it’s super easy to do a data backup of your files in case disaster strikes — all you need is a USB drive and the software built into macOS.
Yes, I know, you could back up to the cloud. If you want to do this, I recommend Backblaze — nothing beats having a backup you can hold in your hand (and maybe keep safe in a fireproof safe or offsite).
The software we are going to use here is Time Machine.
Ideally, you want a USB drive that has double the capacity of your Mac’s drive, as this will allow for rolling backups, but in a pinch you can use a drive that’s the same size as your Mac’s storage drive, or even smaller, depending on how much data you have.

Tip: Here’s how to find out how big your Mac’s storage drive is, and how much data it has on it.
