The Story
I spend a lot of time on the road, so my laptop is usually Wi-Fi tethered to my Android phone with a pretty stable 50-80 Mbps 4G+ connection and a sweet 90 GB data plan. Both devices run an open source software called Syncthing which syncs, among other files, photos I’ve taken on the phone, and music I’ve added on the laptop.
The thing is, I don’t really want to spend all that data on synchronization, and neither do I want to manually sort things out, every time I connect. Also, I’m not willing to give my files to a 3rd party, just for the convenience of synchronizing it - encrypted or not.
Meet Syncthing
Unlike Dropbox, Syncthing does not rely on servers to store, or synchronize your files. It doesn’t even require any sign-up, accounts or passwords. You simply install Syncthing on the devices you’d like to synchronize, and literally add them to each other. This is as easy as scanning a barcode on your laptop with the application on your phone.
We’re not done yet: Because I’m usually tethered to my phone, getting a 4GB video recording from my phone, to my laptop, takes less than 30 seconds, and about 12 kb of mobile data. Everything happens automatically, in the background and within seconds of them being connected, directly over the Wi-Fi connection.
While Dropbox supports LAN sync, your files will ultimately end up on their cloud. With Syncthing, you data stays on the devices you’re synchronizing. All settings are configured client-side and new connections have to be approved by you. That also means, that you can easily share files and folders with friends and family.
If you still want to run a sync server, simply install the Syncthing client on a 3rd device.
Bonus
Syncthing comes with a lot of features, but one I very much appreciate is the file versioning. You can configure Syncthing to keep X GB of recently deleted files in a hidden folder, so if someone accidentally removes something, you can easily recover it on your end.
Final words
While Syncthing is free to use, I’d suggest you to donate on their website, to fund development and discovery servers.
Update: 2018-07-30
It’s been over 4 months since we’ve started using Syncthing at SEDVentures. We’ve got a central server, that basically manages all shares, so we don’t have to rely on individual clients to be online, for their files and changes to sync to other employees.
The setup is rock-solid, and we retain 100% control over our data. On top of that, we save money and have some great file-retention features.
