Why you should backup your stuff before you upgrade to iOS 10.3

Apple just released iOS update 10.3.  Its got some great AirPods support features and some nice upgrades for Siri and CarPlay.

What they don’t tell you is that they are updating the file format to a whole new structure called the Apple File System (APFS)  It is meant to help developers with a variety of things “include strong encryption, better manage large chunks of data, improve time stamps, save space, and help protect files from crashes.”  Great, right?! Well, yes and no.

The not-so-great is that if during the upgrade your files are corrupted, they are gone for good. No possibility of recovery.  You can’t even grab an old backup and transfer it over since it’s in the old format.  If something goes wrong during the upgrade you may have to reformat you phone and lose all your files!  So, BACK UP YOUR PHONE BEFORE INSTALLING iOS 10.3!!!
