what is nut-backup fr?

This repository is a single shell script called nut-backup.sh, built for people who run a Proxmox server with NUT, short for Network UPS Tools, the software that monitors a battery backup power supply and lets a server shut down gracefully during a power outage. Rather than being a full application, the script's only job is to gather up everything useful about the current NUT setup and package it into one backup archive. The archive it creates includes a copy of the entire NUT configuration folder, a record of which versions of the NUT and SNMP packages are currently installed, the current status of the NUT service, information about the server's network interfaces, information about connected USB devices, and a snapshot of the live UPS data pulled from the upsc command line tool, which normally reports things like battery charge and power status. Using it is simple: make the script executable and then run it as the root user. The README provided is quite short and does not go into detail about where the resulting archive is saved, what format it uses, or whether the script accepts any command line options, so those specifics are not covered here. This is a small, focused utility rather than a general purpose backup tool. It is aimed at Proxmox administrators who want a quick way to capture their UPS monitoring configuration and diagnostic state, for example before making changes or when troubleshooting a NUT installation.
