For the administrator who runs the UrBackup server underneath St0r: what the interactive installer does when UrBackup is missing or already there, the permissions and storage path St0r depends on, UrBackup's ports, pre-configured client installers, and setting up internet clients (home workers and laptops) with the right port and per-endpoint internet settings.
