This backup program has been a problem from the start. When it first did a backup of my main house computer it did not do a full backup but did a pick and choose mostly of my profile. I had paid extra to have an external drive sent to me to do this initial backup to. As for our iPhones it just does photos, videos, documents and contacts. What about music??? If you have an iPhone I bet you have music on it. I just got an iPhone 6S and it didnt ever finish the first backup, I have left the phone connected to external power for a full half day and it still says it has done 44 of 50 files. Very bad experience with this program.
