Oops-a-Daisy

There are tons of inexpensive backup programs out there, especially for home use, but they all have limitations when it comes to past versions of your files and folders. That's why Oops!Backup is so unique...it's basically like Time Machine (the Mac backup system) for Windows, as it can store unlimited versions of files you overwrite or delete. Very slick. The trial is for 30 days, and it only costs $37 to purchase.
