Ashampoo’s dated (e.g., ‘2020’) products are usually stripped-down versions of their main product (e.g., ’12’ for this one – their current version is now ’14’ but is for some reason priced at $25 rather than the current price of $31 for ’12’). Check out their product descriptions to see how they differ (one of the ways might be in their support for the ‘Infinite Reverse Incremental’ technology which I believe they picked up when they bought Ocster Backup about four years ago).
