rSync Files on Interval

Sync media to Raspberry Pi or any ARM SoC.

A recurring requirement for my IOT projects involves keeping a set of files synced with a central server. Many of these projects include media players, kiosk systems, or applications that need frequently updated configuration files, all while entirely unattended, and in most cases unreachable through firewalls. I have one project that alone has 2000+ devices pulling media continuously from an rsync server. Many of these devices are on doggy wifi networks.
