I'm trying to sync some folders to raspberry Pi. 

For now, I have a script that gets the dropbox folders using curl that runs every so often using `cron` (once every hour for most of the folders).

I'm wondering if there are any better solutions (perhaps that check if the folder has changed since the past sync).


I'm running a very lightweight Arch distribution and I don't want to install the official dropbox app (which I'm not even sure will work on arm), because it has a lot of prerequisites.
