Sync to my own server for contacts, sms and notes?

> **Possible Duplicate:** > [Suggestions for syncing data to someone besides Google? Funambol?](https://android.stackexchange.com/questions/7774/suggestions-for-syncing-data-to-someone-besides-google-funambol) Does anyone know any effort on Android which can sync contacts, sms or even notes/todos to my own server? I saw similar function on Samsung GS3 "Add account" settings page but not sure how it works. All advice are appreciated. Preferably open source projects. Thanks!
