What is N+1 redundancy and why does it matter for remote sites?

N+1 redundancy means deploying one additional full-capacity backup generator beyond what is needed to cover the site's load. This ensures that if the primary unit fails or needs maintenance, the backup takes over without interrupting critical systems. Sparkline Group specifies this approach for genuinely critical remote applications where downtime is unacceptable. It removes dependency on any single machine performing flawlessly at all times. This is particularly important for facilities far from rapid technician response.
