Warning: Lost a big PDF with notes and comments, never trust Document Cloud!
I am really, really angy and just wanted to warn other users: I used to save big documents and PDF books in Adobe Document cloud and comment on them. This way I could access them from multiple devices. Because I don't trust any cloud service 100% I used to make backups from time to time which unfortunately includes many manual steps when using Document Cloud. Unfortuantely, my last backup was made a couple of days ago so I lost a lot of work.
What happend yesterday was something that I really did not expect from a so called "professional" document (!) cloud service: Acrobat DC became completely unresponsive during a save of the big PDF document into the cloud. After restarting I thought that I can simply reopen the doc but then I got a simple message that the file is damaged and cannot be recovered. Everything was simply gone! There is no backup and there is no way to recover the document. What I did not expect is that Document Cloud removes the last working PDF before having saved the new version successfully. I regard this gross negligence on Adobe's side and I am really angy how such a thing is possible to happen...
