Introduced in 2016, APFS is Apple's forward-thinking file system that it uses across practically its entire device ecosystem. With the introduction of macOS Big Sur, iOS 14, and iPadOS 14, Apple will be making it even more useful for users, by adding support for APFS in a few new areas.
Even though Mac computers are capable of reading hard drives that are formatted for Windows, if you intend on using your external HDD as a bootable disk or want to use it to backup files with your Mac's Time Machine, you must format it to be entirely Mac compatible. Time Machine was designed to work with external hard drives and not cloud based systems. I suggest you try using a clone backup instead of Time Machine. Clone backups can be configured to run automatically. Clone - Carbon Copy Cloner (Often recommended as it has more features than some others) Clone – Data Backup. Clone – Deja Vu. Once Time Machine's first backup to the first drive is complete, disconnect it from your Mac completely. Attach the second drive and repeat the steps above. Switching between Time Machine disks requires virtually no effort on your part, but you don't want to connect both Time Machine disks simultaneously. To back up different Macs using Time Machine, you can: Do it manually. Perhaps the simplest way is to attach the drive to one Mac, let Time Machine run a backup, then disconnect the drive and repeat the steps on another Mac. In each case, Time Machine works behind the scenes to get the job done. The best Time Machine hard drives for Mac. Setting up iCloud storage is a pretty straightforward process. You just choose the amount of data that's right for you and then move your files to the iCloud Drive folder in Finder. Time Machine, on the other hand, is a bit more involved, especially since you have to pick out the right external drive.
On macOS Big Sur, Apple is finally bringing the ability to use an APFS-formatted drive with Time Machine, 9to5Macreports. With macOS Catalina and earlier releases, users were able to back up to an HFS+-formatted disk but not an APFS-formatted version, with macOS offering to reformat the drive to HFS+.
Under Big Sur, users will be able to back up directly to an APFS-formatted drive, eliminating the need to reformat any disks.
For iOS 14 and iPadOS 14, Apple has plugged a hole for external drive support for one specific use case: APFS encrypted drives. While it is currently possible to view external drives in a number of common formats from an iPhone or iPad, it only works for non-encrypted drives, with encrypted drives being unreadable by the mobile devices.
On connecting an encrypted APFS drive to iOS 14 or iPadOS 14, the drive will appear on the updated Sidebar, with a selection of the drive bringing up a password prompt to decrypt it.
The added support for encrypted drives will only work for APFS-formatted drives, which may still be a limiting factor for some users in a multi-platform environment.
