If you run out of disk space, Time Machine will automatically erase the oldest version of the files to make way for the new ones. You'll need a drive that is at least the same size as your Mac's internal drive.

Step 1: Boot Into Recovery Mode

With storage quite cheap these days, aim to use a drive that's two to four times the size of the drive you're backing up. You can also use Time Machine with an external hard drive connected to an Airport Extreme router, with an AirPort Time Capsule network device, or with other network drives. For simplicity's sake, we're using an external drive for the examples below.

Directly connected external drives are also faster. Then click the "Select Disk…" button to select the drive or volume you want to use for Time Machine. Time Machine will ask you if you want to use the disk as your backup destination and will give you the option to encrypt the backups with a password.

The drive needs to be formatted as Mac macOS Extended Journaled ; if it's not, Time Machine will prompt you to reformat the drive which will erase all files on it! The "Options" button in Time Machine will let you exclude volumes from the backups or get notifications when old backups are deleted. To view and restore files or folders from Time Machine, go to the Spotlight search and enter "Time Machine" to switch to the Time Machine view. Here you'll be able to scroll through the timeline on the right site to go back to a certain point in time or search for a file.

With a file highlighted, press the space bar to get a quick look of it or click the "Restore" button to copy the file back to the appropriate folder. In case of filename conflicts, you'll be asked which file to keep or whether to keep both versions.

Make sure your drive is properly formatted

Time Machine can also restore your entire system at once, using the latest copies of all your files. Then select "Restore from a Time Machine Backup. You can't really rely on Time Machine for a complete full-system backup, however, if your startup disk is damaged and you can't boot into your Mac. For times like these, you'll need to have a clone or complete image of your system.

Make sure your drive is properly formatted

A clone is an exact duplicate of your entire system. With a bootable clone of your drive, you can boot from your backup in minutes and keep working even if your Mac is having startup problems. We want to make sure backing up is as automatic and as easy as possible, so either program is well worth the investment. Both cloning apps have plenty of fans, so it's really a matter of preference here; both SuperDuper!

In the left drop-down menu, choose your Mac volume to back up. Then choose the destination volume in the right drop-down menu. You can back up to an external drive, networked computer, or an image file which you can store on a network volume or locally. You can even store both your Time Machine and cloned images on the same drive, but it's best to first partition the drive into two volumes, one for each purpose so that both can manage their allotted backup space. Personally, I prefer to have both on separate drives, to avoid having all the backups in the same basket.

Choose "Backup-all files" for your complete and bootable backup of your system.
