Thanks. It also exemplifies why no one should ever trust iCloud, GoogleDocs or any other online storage service for their key documents without a backup they control entirely!
Currently, ALL the 'cloud storage' sites offer free storage in exchange for free access to ALL your stories, and they also reserve the rights to everything stored there, including deleting the account with no notice.
The only exception is DropBox, which keeps their paws off of the data stored there. However, that will only last as long as the current owners maintain ownership. One of these days, one of the other sites will offer them hundreds of millions and they'll hand all of your data, but currently, they're resisting the impulse to capitalize on them.
Also, back up ALL your data! You never know when a computer, HD or computer infection will fail (here's hoping the infections fail!), and all your data since your last update will be gone.
I'm a bit obsessive, backing up to a spare HD on my computer, a bunch of external drives and USB sticks and dropbox. Yet I still forget to back up on occasion. I lost several chapters over Christmas when my solid state HD died (no way to recover on those). It was only months later that I discovered I'd also lost an entire unfinished story. Lesson only partially learned.
