What It Does Reads device list from devices.yaml (hostname, IP, credentials, device type) SSHs into each device using Netmiko Runs show running-config and captures output Saves each config as {hostname}_{YYYY-MM-DD_HH-MM}.txt Logs success/failure per device to backup.log Sends an email summary when complete (optional) Built initially to run nightly via cron across MSP client sites.https://7f57629a.jeremiahwindle.pages.dev/blog/ccna-study-plan/Thu, 15 Jan 2026 00:00:00 +0000https://7f57629a.jeremiahwindle.pages.dev/blog/ccna-study-plan/Target date: June 2026. Here’s the actual plan — resources, schedule, lab setup, and where I’m struggling. Why the CCNA Matters for Me Specifically I’ve been managing Cisco Meraki, Fortinet, and UniFi networks across 40+ client organizations for four years.

The CCNA doesn’t teach me most of this — I’m already doing it.
