+Have you heard of the [3-2-1 backup rule](https://gitprotect.io/blog/3-2-1-backup-rule-complete-guide/)? The idea is simple but powerful: if your data doesn't exist in at least **3 places**, it doesn't really exist. More specifically, the rule says:
+
+- **3** copies of your data
+- **2** different storage media (e.g., local disk + cloud)
+- **1** copy stored off-site
+
+It's a well-established baseline in the industry, and some organizations even extend it to a 3-2-1-1-0 model — adding one immutable or air-gapped copy and zero unverified backups. Despite how long this rule has been around, a surprising number of people (and teams) still don't follow it.
+
+This week's (2026-05-12) chat we want to talk about backup habits — at home, at work, for your personal projects, wherever. Some discussion starters:
+
+- Do devs take better care of their data and have better backup habits than non-devs? Or does knowing how things work make us *more* complacent ("the cloud handles it")?
+- Do you have your own system for protecting your data? What does it look like in practice?
+- Any nightmares or lessons learned the hard way?
+
+Everyone and anyone is welcome to [join](https://weeklydevchat.com/join/) as long as you are kind, supportive, and respectful of others. Zoom link will be posted at 12pm MDT.
