Apple’s cloud backup for iPhone, iPad and Mac users may have a serious flaw that could unexpectedly permanently erase files. Worse yet, if you synched all your Apple gadgets together, your files could disappear from all of them.
In the wake of Apple's difficult post-launch days (#bendgate, failed iOS 8.0.1 update, and the Shellshock virus attacking Macs) there seems to be one last problem Apple and its users must deal with - it's an iOS 8 bug that can erase all your iWork documents from iCloud.
I know, "great."
So, word has it that the "Reset All Settings" option found under Settings>>General>>Reset in iOS 8 also (not so conveniently, either) deletes documents from the iCloud drive - permanently.
Matters are made worse by the clear statement (for a function intended to reset factory default settings) that "no data or media will be deleted." Whoops. Now, if that were not enough, if the device running iOS 8 is synched with a Mac running OS X Yosemite - you guessed it - all iWork documents stored on iCloud were gone.
