I really love using BitTorrent Sync for syncing very large files, but there is one thing that is driving my crazy and that is the lack of a backup and restore feature for the settings, folder locations, keys, etc. I have a tradition of erasing my entire hard drive and starting from scratch when a new OS update comes out. It gets really annoying trying to manually copy and paste all the keys. It would be really awesome if there was a backup and restore function for BitTorrent Sync; where you can select the secrets you want to restore and change the directory to different location if needed. I really hope you consider this feature. It would make BitTorrent a flawless experience for me.
