Syncthing is a useful option for people synchronizing folders between their own computers. Pair two devices and share a test folder before adding large or important working directories. Start with a small, representative task so you can check the results before extending the setup.
Choose folder modes and versioning deliberately, and retain an independent backup because synchronization can spread unwanted changes. Consider the practical trade-off: deletions can synchronize too.
