First, thank the developers for this awesome solution. Great idea and software, crossplatform and independent. I'm using it for many purposes. Having a server at home, the server and BTSync benefit from each other. BTsync is installed on the server, but also all other devices: smartphones, tablets, laptops and the business related computers with different share options, building a good backup solution for all these. But backup is not the primary reason for BTSync. Since the mobile devices are connected, updating the image database is automatic, scripts move the pictures around keeping the memory on the phones free and storing all on the server and big machines. The server is mainly a weather server (www.meteo.casacota.cat) connected to several weather stations around the Pyrennees building the central database for all them. With BTSync I can share the data not only via website but also bigger databases with different people interested, avoiding manual mails with attachments sending. On the other site I'm teaching in a school and dealing with many and big audiovisual files, pro semester about 20 GB, to be shared with more than 100 students. BTSync is used to share all these files, with support from an external BTSync server, https://incloudibly.com/en/syncservers to speedup sharing since the main server has a poor connection being located in the mountains with only a radio link. This makes 18 different Sync folders with about 500000 individual files and around 500 GB data. Earlier I tried other solutions like dropbox, spideroak, copy and others, but all where very slow and otherwise limiting: bandwidth, CPU and resources consumption, limited in the configuration (read-only folders are a must), BTSync addresses this all and does'nt slow down any machine, specially with unencripted TCP for NAT connections. In short, BTSyng is changing the life... thanks!
