I had a few minutes today to do a Google search or two and added to the Livedrive resellers list on the Livedrive review page. In my searching I discovered that Backify was not the first Livedrive reseller to offer such a large free account. BeeCloud also offers a large free account. They have been around slightly longer so if you are looking for a company with the same features you might want to check them out as well.
Before signing up for any of these services please be sure to read the comments on the Livedrive review page.
Here is the current Livedrive reseller list.
