As I mentioned in other threads, DropBox is rolling out a gradual update of their interface. The upgraded accounts (those in www2.dropbox.com) are no longer compatible with Akeeba Backup. Unfortunately, until my own account is upgraded I can not even begin on working on a new DropBox integration. At this point in time I have no idea if the new (upgraded) accounts will ever be compatible with Akeeba Backup or if I will have to remove DropBox from the list of supported engines.
The official API is completely unsuitable for anything over a few dozen kilobytes, making it impossible to use with very large backup files (unless you have servers with 2Gb of max PHP memory, i.e. over 1Tb of total RAM - i.e. not going to happen in this decade!!!). As a result, I have to use a workaround which involves code which tries to simulate an interactive login and web upgrade. This is exactly what broke with the recent DropBox upgrade and I am not sure if the new interface will allow me to create a new compatible solution. If that's not possible, DropBox support will be dropped.
