Currently I am syncing a Linux directory to Windows folder via Dropbox.
However, I want to pursue an opensource alternative to this approach since I don't want to files on Dropbox server.
Are there any similar tools or approach I can use to do the sync in low latency fashion (beside Rsync?)
An option that you can explore is to script it to copy the files or directory you want. You can then schedule it as a cron job to automate the process for you.
If you want something similar to dropbox you can setup a owncloud Server. It's open source and works the same way. Have a look here https://owncloud.org/
