Another Dropbox horror story: My colleague lost most of his Dropbox folder last week, and wasn't able to recover everything. What happened: he had Dropbox synced to 2 computers, but one of them hadn't been used in a while. He turned on the old computer, and apparently, for some reason, Dropbox decided that the fact that many files weren't there was because they were deleted. Of course, the files weren't there because…
My approach for Dropbox on both Windows and OSX is to have the Dropbox folder on a drive that will never see development work, even if that means creating a separate partition for it. In most cases the system drive works fine (you do have separate system and data drives on your machines, right?).
This forces a COPY operation rather than a file MOVE if you drag-and-drop files into any Dropbox folder. Which means that everything in the Dropbox folder could be trashed tomorrow and nothing whatsoever would be lost.
On Windows you can also do this by dragging files while holding down the RMB and on OSX while holding down the Option key. This, however, is fraught with issues because it is easy to forget and move something in or out of Dropbox accidentally.
In addition to that, daily system and data backups to external media on EVERY SYSTEM in the office ensures that even if you took a sledge-hammer to any given machine all the data could be recovered to within a 24 hour boundary.
So, no, this is NOT a "Dropbox horror story" as far as I am concerned. At best this is an unfortunate "pilot error" and at worst this is a sign of incompetence.
Sorry, a little harsh there, but, as a student, I lost six months of heavy coding work once in college. That really hurt. And that was probably the best time and place to learn that lesson. That is all it took for me to be completely insane about having backups of backups on anything important. Now, may years later, you will not find any critical system in my office that is not backed-up at least once and usually twice.
These days there's almost no excuse for loosing your work. Don't go around blaming Dropbox, not their problem.
I am not associated with Dropbox in any way other than being just another user.
FEATURE REQUEST: It would be very nice if Dropbox client software could have an option to auto-magically COPY files in and out of Dropbox rather than allowing any files to be moved. The above-mentioned hack works fine but it'd be nice to not have to use it. Also, I'd venture to guess that most Dropbox users don't do this, which opens them to unintended loss.
