I purchased this tool hoping for an easy/secure/encrypted backup solution which would be easy to setup and easy to recover my data if necessary. During tests, the filter methods are completely different than any other product on the market and none of them are documented. The developer did return one of my emails to answer this question, but the methods they gave me were documented NO WHERE (not even on their web page), and, when I asked if these details were documented somewhere, they did not return my email. Also, after sync’ing a set of files and encrypting them during the sync, how do you decrypt them? It seems there is no method to do this - you can sync and encrypt, but, if you need to get the data back, there is no method to decrypt. Pretty bad Greenworld….
