Hey, thanks for commenting! Dropbox does have a sort of version control but it only keeps files for about a month (and even then you wouldn't want to rely on it if you definitely wanted the files back!). And even if all the revisions of the files you want are still in Dropbox's memory you'd still have to figure out which which you needed for every file (potentially a problem in a folder with hundreds or thousands of files!). AWS going down definitely isn't the only reason you might lose data from Dropbox, in fact it's probably one of the least likely. Far more likely is accidental deletion (delete it on one computer and Dropbox will delete it on all your computers!) or file corruption (which you might not notice for months). Even so tidy.io stores a copy of every file on Glacier which is a separate system to the S3 service that Dropbox uses
