What can be said about the ability of Sync to handle extremely poor and unreliable network conditions? A normal BitTorrent download can typically be interrupted and restarted without losing what has already been downloaded. But I am trying to use Sync to move files internationally while using slow or unreliable WiFi connections and have found that Sync must "start over" from zero when the transfer of a big file is interrupted. I was hoping that it would be more robust. Could somebody comment on this or point me to any existing threads or resources about this issue? Thank you.
