It may have already been used as a backup system, but it was not made for that, and they even answered that in their FAQ. It was this question that stopped me setting it up, because it made me realise I was after a backup solution, not just a synchronisation tool " Is Syncthing my ideal backup application? No. Syncthing is not a great backup application because all changes to your files (modifications, deletions, etc.) will be propagated to all your devices. You can enable versioning, but we encourage you to use other tools to keep your data safe from your (or our) mistakes.
