Difference between Btrfs and ZFS

Btrfs vs. ZFS

Btrfs (pronounced as "butter fuss", "better F S", "butter F S", "b-tree F S", or simply by spelling it out) is a file system based on the copy-on-write (COW) principle, initially designed at Oracle Corporation for use in Linux. ZFS is a combined file system and logical volume manager designed by Sun Microsystems and now owned by Oracle Corporation.

Apple File System

Apple File System (APFS) is a proprietary file system for macOS High Sierra and later, iOS 10.3 and later, tvOS 10.2 and later, and watchOS 3.2 and later, developed and deployed by Apple Inc. It aims to fix core problems of HFS+ (also called Mac OS Extended), APFS's predecessor on these operating systems.

Copy-on-write

Copy-on-write (CoW or COW), sometimes referred to as implicit sharing or shadowing, is a resource-management technique used in computer programming to efficiently implement a "duplicate" or "copy" operation on modifiable resources.

Data compression

In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation.

Data deduplication

In computing, data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data.
