A capable self-hosted and FOSS replacement for Dropbox, Google Drive, etc.
This all sounds great, however the one major downside to Syncthing is its lack of mobile application. This kept me from using it for quite a while until I finally found a workaround (at least for iOS). Enter Secure Shellfish3. While it looks like a run-of-the-mill SSH client for iOS, it has a nifty feature of allowing you to mount a remote device onto iOS’s Files app. If you have an always-on server running Syncthing you can use this as your mount device to get mobile access to your files. iOS’ Files app has all of the normal filesystem features you’d expect: uploading, downloading, scanning documents in, etc. The experiences ends up being pretty seamless.
I don’t have a similar recommendation for Android users just yet, but I’m sure something similar exists. If you’re reading this and end up giving it a shot, send me an email and let me know what has worked for you so I can post it up here.
While the redundancy of having my filesystem in sync on multiple devices is pretty safe for ensuring no data gets lost, I also fall back to BorgBackup to ensure I have an entirely separate off-site backup. You can read more about this setup here (ctrl+f for the borg section).
The one I stuck with the longest and recommend if you’re unwilling to go down the Syncthing path is Tresorit. Note that I selected this service quite a while ago and there may be companies offering a more secure solution these days. My biggest gripe with them was that their client software was all closed source. ↩
I have not tested this personally and cannot fully vouch for it being 100% safe/leak free. ↩
The app is paid but I have no affiliation with the developer. ↩
