BupBox is a suite of tools for building a "backup appliance" capable of serving a home or small office. It is optimized for one and only one use case: a pool of PCs push backups to a master BupBox server, which then mirrors to other remote BupBoxes. If this sounds like your situation, you couldn't make a better choice ; )
The following network diagram may help to explain BupBox usage, in its most complicated state. The only "required" components are a single client, and the BupBox master server (in green).
