A few years ago I decided to give up on sdcards for my main 24/7 homelab server.

I now use a small SSD connected via USB3 and a slightly modified version of this : https://framps.github.io/raspiBackupDoc/introduction.html

...to take snapshots to my NAS periodically.

I keep a similar small SSD in the drawer ready for a restore and swap if the main system drive fails.
