Time Machine Backup External Drives

Time Machine is a great feature that automatically backs up your Mac's hard drive at set intervals. It's an excellent way to make sure you don't lose any data and to have back up data if you're ever forced to do a clean install. If you have an external hard drive connected to your Mac via USB, Time Machine will also back up any changes you make to files on that drive. Browse the top-ranked list of Time Machine backup external drives below along with associated reviews and opinions.

FAQ

A Time Machine backup external drive is a storage device that is compatible with Apple's Time Machine software, allowing you to automatically back up your Mac's data, including files, apps, and system settings.

Yes, most external drives need to be formatted to the APFS or Mac OS Extended (Journaled) file system before they can be used with Time Machine. This can usually be done easily using the Disk Utility app on your Mac.

Yes, you can use the same external drive to back up multiple Macs with Time Machine. Each Mac will create its own backup folder on the drive, keeping the backups separate.

Most external hard drives and SSDs are compatible with Time Machine as long as they can be formatted to a compatible macOS file system. It's recommended to check the drive's specifications for macOS compatibility before purchasing.

Yes, you can store other files on your Time Machine backup drive, but it's best to create a separate folder for personal files to avoid interfering with the backup process.
