In this episode of Linux Server Admin, Lucas and Luna dig into the practical side of backup strategy for Linux servers. They break down the 3-2-1 rule, compare full, incremental, and differential backups, and walk through a real-world scenario using rsync and a LUKS-encrypted external drive. They also discuss testing restores, common pitfalls like silent corruption and backup drift, and share a quick tip on automating backups with systemd timer units. If you've ever wondered whether your backups would survive a real disaster, this episode is for you. The conversation stays grounded in day-to-day sysadmin reality, with concrete commands and thinking that you can apply immediately.
