What’s not to like? Dropbox is inexpensive, automagically synchronizes a folder of files between devices, and it just works. The only problem is that Dropbox is an online sync and storage service so there’s no easy way to know when something goes wrong, or someone tries to hack your account, or alerts you when one device doesn’t sync like it should, or finds files that once were but now are not.
Here’s a free solution for Mac users. It’s called Revisions. I think of it as Time Machine for Dropbox, with a big, giant undo button to bring back files that may have been lost.
Like Time Machine on OS X, just install Revisions and let it do its work. If you need to see which files have been revised, use Revisions.
While Dropbox stores all versions of your files and folders for 30-days, you need a paid account to store your Dropbox account’s entire history of file and folder revisions. Revisions gets you the same access but on your Mac.
Revisions is simple to setup and use, intuitive, and can be both a lifesaver and moneysaver should a few file revisions go missing in action.
