Time Machine stores multiple copies of files and every time you change something, like a document, photo or video, it saves it as a separate version.

That leaves 350 GB of unused space on the 500 GB drive. It does not have to be the same exact size, just big enough to store all the files. The macOS partition is 154 GB, so I set the partition size to 150 GB. The first partition will be used for SuperDuper! backups, which is basically a clone of the Mac’s internal drive.

You may need a bigger backup drive if your Mac’s internal drive is bigger than mine or you may be able to allocate more space to various backups if your USB drive is bigger. Mac and backup driveĭrives come in a wide range of capacities and yours may be different to mine. This is the way that I use mine and it is a bit unusual, so it might give you new ideas for ways in which you can use your own backup drive. There are many ways to use a backup drive and there probably isn’t a best way. If you can afford a big SSD for a backup drive, then go for it, but an HDD is fine. They are much slower than solid state drives (SSDs), as used in MacBooks these days, but this matters much less for an external backup system than it would for an internal drive.
