The 'journaled' feature on this file system refers to a way of storing media on the disk. And it continued as the default Mac OS X file system until APFS replaced it. This file system is an upgrade of HFS (HFS Standard or Hierarchical File System). It is the file system used on all Mac OS 8.1 and later, including Mac OS X, since 1998. Mac OS Extended (Journaled) is also known as HFS Plus or HFS+. Apple has also designed it for optimizing access to solid-state drives (SSDs) and flash storage devices.įrom macOS 10.13, APFS has become the default file system of Mac hard drives (or startup disks).ĪPFS volumes also enable snapshots for creating a point-in-time and read-only instance of the file system, which can be a backup of your data.įor Macs with SSDs before 2016, they have auto-converted to APFS when upgrading the macOS. APFSĪPFS, short for Apple File System, was introduced with the launch of macOS 10.13 (High Sierra) in 2017. But they have differences in some aspects. They control how data stored and retrieved on a storage device, such as hard drives.

What is APFS and Mac OS Extended (Journaled)ĪPFS and Mac OS Extended (Journaled) are file systems for macOS. What format option is better, APFS or Mac OS Extended? What is APFS and Mac OS Extended (Journaled) Mac OS Extended ( HFS+)? Are you confused about which one you should choose for disk formats? Please read this post to get the answers. Instead, you seemingly can only backup over the network to an old-school Mac OS Extended (Journaled), known more familiarly as HFS+.īecause Disk Utility can adjust partition sizes non-destructively after they are created, you don’t need to erase your Time Machine drive, but can add an HFS+ partition.How much you've learned about APFS vs. While it can mean many things, in the context of Time Machine, it typically means that you are trying to back up to a Time Machine volume on an APFS-formatted partition. You do not have the necessary read, write and append privileges on the selected network backup disk.Īpple doesn’t document this error on its support site, which is a pity. If you format that disk only with APFS partitions, you will try to follow the steps to use it from a network-connected Mac, and receive the following complicated warning: But if you have a desktop machine to which you can easily attach a fixed, high-capacity drive, you can make that drive a Time Machine destination for other Macs on the network. Time Machine can work by backing up to a drive attached directly to a Mac. But Apple omitted a big footnote that should be in its documentation: An APFS-formatted volume can’t be used for networked Time Machine backups. In macOS Big Sur, Time Machine added support for backups onto APFS-formatted volumes (the filesystem that Apple introduced a few releases ago).
