Comment summary: Syncthing is widely appreciated for its decentralized, open-source nature and ease of configuration for file synchronization across multiple platforms including Linux and Windows. Users value the security and privacy features but note that the Android app is inconsistent, lacking automatic sync capability. While it works efficiently once configured, some users find the initial setup process complex and unreliable at times. Concerns about recent project funding and politics have been flagged.

SyncTrayzor will encapsulate SyncThing within a regular program window. Can be closed and/or minimized to tray and start-up minimized as well. You can still access the web interface if desired. The SyncThing executable keeps a (ugly) taskbar slot constantly open, SyncTrayzor fixes this. Get it here, https://github.com/canton7/SyncTrayzor Also, I would like to add that it works just fine on Windows 10 x64 (TP-10130) without a hitch.

I sought out an alternative to Bitorrent Sync and SyncThing+SyncTrayzor takes care of my needs.

Thank you for mentioning this utility! My biggest issue with SyncThing was having to keep a terminal window open all the time.

If you are using Linux (terminal?) you can run it with "screen syncthing". Then just press Ctrl + AD and you have it in the background. Get screen by inserting "sudo apt-get install screen" if you are running debian-based distros like me.

Automatic crash reporting. See https://github.com/syncthing/syncthing/releases/tag/v1.2.0 This costs it 2 stars. The feature appeared today. Upon starting up the app on 2 of my PCs, a message appeared giving me an opportunity to opt out. On a 3rd PC, which runs around the clock, with Syncthing always on, I did not see a message to opt out. To disable automatic crash reporting, according to https://docs.syncthing.net/users/crashrep.html , one must go to "advanced configuration dialog" (not "settings," which only allows one to set anonymous usage reporting). When you click on advanced configuration dialog, a window opens with the following warning: "Be careful! Incorrect configuration may damage your folder contents and render Syncthing inoperable." When I checked, there weren't other instructions. I clicked on "options," and a number of settings appeared. One of these settings, Crash Reporting Enabled, was unchecked. I am going to presume that Crash Reporting Enabled is the same thing as automatic crash reporting. So, for my 3rd PC, apparently, I have not received an opt out notice but crash reporting has not been enabled. Maybe this will change if I restart this PC at some point (I already restarted Syncthing several times)? I don't know, but this will be one more thing that I am going to have to check for a while. Disenchanted long ago with Resilio, I have been using Syncthing. Today's change is disappointing.

Amazing sync solution, although not as fast when connected to a VPN in my experience

I wish the sync conflicts were more clearly communicated / listed somewhere. Other than that, great service.

For a novice home user, SyncBack seems like a much easier option than this program to set up synching a drive to a usb attached drive.

What is Syncthing?

Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet.

Private. None of your data is ever stored anywhere else other than on your computers. There is no central server that might be compromised, legally or illegally. Encrypted. All communication is secured using TLS. The encryption used includes perfect forward secrecy to prevent any eavesdropper from ever gaining access to your data. Authenticated. Every node is identified by a strong cryptographic certificate. Only nodes you have explicitly allowed can connect to your cluster.
