Backup4all comes in three editions: Professional, Standard and Lite. You need one license per computer. For more information about the differences between each edition, see the Compare Editions page. If you already own a key, you can Extend it with more licenses or Upgrade it.
Note: Volume discounts apply only if multiple licenses are purchased on a single order.
Purchasing a license requires a one-time payment (no subscription fees). A license grants you free priority support and free minor updates (i.e. from version 8.x to 8.9). Prices are in United States Dollars ($).
