iOS 10.3 promises to deliver a host of new updates, one part of the update could hurt users who do not back up data and files to Apple’s cloud before installing new iOS.
It has to do withApple introducing a new file system to replace its 29-year-old predecessor known as HFS+.
Your iOS update will automatically convert to the new Apple File System (APFS), but if something goes wrong during the process, your old files could disappear for good because the two file systems are not compatible.
While you will be able return to the old version of iOS, this will require you to reformat your drive, which will delete all of your files on your device — hence the need for the backup.
It canrisky, but Apple File System promises to be a huge improvement on the predecessor which the tech giant has been using its introduction in 1998.
