6/21/2023 0 Comments Apple os x file system![]() That means, if you are backing up large amounts of data on OS X the underlying data can change during the course of a single backup if files are re-saved or left open. HFS+ can not create disk snap shots which are like an on disk backup of data from a point in time – ZFS does. That means ZFS can automagically recover files from non-function parts of a disk – which is actually a fairly common occurrence. HFS+ does not scrub disks looking for bad blocks or corrupt data – ZFS does. With todays disks now up to 4TB and the massive explosion in the amount of data stored, there are a few critical things needed in a modern file system. Whilst Apple have cleverly added features like hard links, hot zones, auto-defragmentation, meta-data journaling, compression and other features without breaking compatibility, it is not a particularly stable and recoverable file system. ![]() Simply put, HFS+ dates back to 1998 (the year I stared D Revolution) and whilst it has served Apple well, it is missing vital features for a modern filesystem. ![]() Ten’s Compliment have a File System plugin for Mac OS X that allows the use of ZFS instead of the standard HFS+.Īfter a year of following a startup company full of ex Apple engineers, they have finally released a product. Sorry for the nerdy nature of the post – it’s often the underlying technology that propels computing forward. Welcome back to the D Revolution blog after a Christmas hiatus.
