In a production environment managing dozens of routers across multiple sites, configuration consistency and versioning were critical. Previously, router backups were performed manually, which introduced delays and human error especially during configuration changes or policy updates.
To automate this process, I developed a Python-based solution using the Netmiko library. The script established SSH connections to each router, executed show running-config, and saved the output with clearly identifiable filenames (IP address and timestamp). I incorporated robust exception handling using NetMiko’s built-in classes to skip unreachable or misconfigured devices. Additionally, I integrated the schedule module to automate the script’s execution at defined intervals. This solution delivered reliable, consistent backups across 20+ routers with minimal administrative overhead.
