It also avoids having to write the change twice, as happens with an HFS+ journaled file system, where changes are written first to the journal and then to the catalog file. This avoids corrupted records containing partial old and partial new data caused by a crash that occurs during an update. Instead of overwriting existing metadata records in place, it writes entirely new records, points to the new ones and then releases the old ones, an approach known as redirect-on-write. Crash protection Īpple File System is designed to avoid metadata corruption caused by system crashes. Data integrity Īpple File System uses checksums to ensure data integrity for metadata. Increased maximum number of files ĪPFS supports 64-bit inode numbers, supporting over 9 quintillion files (2 63) on a single volume.

Encryption Īpple File System natively supports full disk encryption, and file encryption with the following options: There is, however, no interface to mark two copies of the same file as clones of the other, or for other types of data deduplication.ĪPFS volumes support snapshots for creating a point-in-time, read-only instance of the file system. Changes to a cloned file are saved as delta extents, reducing storage space required for document revisions and copies. The Data volume role (usually named "Macintosh HD - Data") is used as an overlay or shadow of the System volume, and both the System and Data volumes are part of the same volume group and shown as one in Finder.Ĭlones allow the operating system to make efficient file copies on the same volume without occupying additional storage space. In macOS Catalina the System volume role (usually named "Macintosh HD") became read-only, and in macOS Big Sur (macOS 11) it became a signed system volume (SSV) and only volume snapshots are mounted. APFS firmlinks lie between hard links and soft links and link between volumes. macOS Catalina (macOS 10.15) introduced the APFS volume group, which are groups of volumes that Finder displays as one volume. Within each container there are one or more APFS volumes, all of which share the allocated space of the container, and each volume may have APFS volume roles. Within the GPT scheme are one or more APFS containers (partition type GUID is 7C3457EF-0000-11AA-AA11-00306543ECAC). Partition scheme ĪPFS uses the GPT partition scheme. It may increase read-write speeds on iOS and macOS, as well as space on iOS devices, due to the way APFS calculates available data. The APFS code, like the HFS+ code, uses the TRIM command, for better space management and performance. It uses 64-bit inode numbers, and allows for more secure storage.
The file system can be used on devices with relatively small or large amounts of storage.

The specification for software encryption was documented later. Īpple released a partial specification for APFS in September 2018 which supported read-only access to Apple File Systems on unencrypted, non-Fusion storage devices. APFS was released for 64-bit iOS devices on March 27, 2017, with the release of iOS 10.3, and for macOS devices on September 25, 2017, with the release of macOS 10.13. 3.3 Compatibility with Time Machine prior to macOS 11Īpple File System was announced at Apple's developers conference (WWDC) in June 2016 as a replacement for HFS+, which had been in use since 1998.3.1 Limited integrity checks for user data.APFS is optimized for solid-state drive storage and supports encryption, snapshots, and increased data integrity, among other capabilities.
