RunSync

Runsync is a tool for cronjobs that are not supposed to run on multiple machines at the same time, but it doesn't matter which machine runs it.

One example is a database backup that can be run on any of the DB servers but shouldn't run twice. In the case of multiple servers they need to share some storage where the sync and lock file can live.
