Apple is Upgrading Millions of iOS Devices To a New Modern File System Today (theverge.com)

Posted by msmash on from the new-file-system dept.

Apple today began rolling out iOS 10.3, the latest point update to its mobile operating system. iOS 10.3 brings with it several new features, chief among which is a new file system -- called the Apple File System (APFS). From a report: It's a file system that was originally announced at WWDC last year, and it's designed with the iPhone, iPad, Apple Watch, Mac, and Apple TV in mind. Apple has been using its 31-year-old Hierarchical File System (HFS) for iOS devices so far. It was originally designed for Macs with floppy or hard disks, and not for modern mobile devices with solid state storage. Even its successor, HFS+, still doesn't address the needs of these mobile devices enough. Apple's new APFS is designed to scale across these new types of devices and take advantage of flash or SSD storage. It's also engineered with encryption as a primary feature, and even supports features like snapshots so restoring files on a Mac or even an iOS device might get a lot easier in the future.

  1. Catch? by nwaack · · Score: 5, Interesting

    Hmmm...this actually sounds like a useful upgrade. Given Apple's recent "innovations," I'm left wondering what the catch is. There must be something in this update that screws over the customer somewhere.

      That sounds reasonable, except for every single part of the statement being a complete falsehood.

  2. About time... HFS+ is crap by Proudrooster · · Score: 5, Interesting

    In an interview at Melbourne's linux.conf.au conference, Linus Torvalds called the standard file system of Mac OS X "complete and utter crap." Mac fans are only slightly outraged, pointing out that HFS+ isn't really "complete and utter crap," rather, it's just slightly crap-ish.

    On a personal level, I have had multiple corrupt HFS+ filesystems, one of which was unrecoverable. I tried switching to exFAT which also proved to be corruptible but repairable. Now I just store any data I care about on a NAS running a linux ext4 filesystem.

    Hopefully, AFS will fix these corruption problems. I have been sending Apple upgrade suggestions for years. Looks like they finally got around to it. One filesystem to rule them all, but will it support upper/lower case?

  3. Don't blame a filesystem for your lack of backup by zerofoo · · Score: 5, Insightful

    If you lose data due to a corrupt filesystem - it's not the filesystem's fault that you didn't backup your data.

    Even if you had the most reliable filesystem in the world - it would, most likely be running on spinning disks or flash media - both fail quite regularly.

    Backup your data frequently and test your backups regularly.

    Will this add any security against NSA / Immigration trying to steal your data?
