I have the latest versions of the iOS & Windows apps. I have a NAS / media server I custom built for myself with Win7 Pro x64 and multiple independent drives - no RAID; nothing too fancy. I have my NAS set to backup many different ways, but I do use BTSync to backup its contents (about 3TB of stuff; movies, photos, mp3s, etc) to another dedicated PC on my LAN. As far as I can see, BT Sync works fine between the two computers. I recently tried to setup Bittorrent Sync to backup my iPhone 5 camera roll - approx. 30GB of photos (yes, really) in around 6,500 files, according to what the BT Sync iOS app tells me. The whole point of this is I'd like to use BTSync to backup my photos to my media server & then delete them from my phone to clear space on it. What happens is that it just doesn't backup ALL photos; and the problem seems limited primarily to more recent pics. For example: - If I save 6 photos from the internet, then open the BTSync app & let it backup, it will backup photos 1 and 3, but none of the other 6. - If I take 4 photos in a row, it will backup one, but not the other three. I've already rebooted my iPhone & NAS countless times and have deleted and reinstalled the iOS app. Both the iOS & Windows apps report the sync/backup as complete, yet it is clearly not. What else should I try? Do I just have too many photos & videos on my iPhone for BTSync to handle? Thank you!
