6 months agoAnother option is to use Image File Utilities on the Pi to create an image backup. You can use cron + a bash script to create incremental backups using the tool (e.g., take a ‘fresh’ backup each month, with daily incremental backups in between). I mount a network ‘backup’ drive (a local NAS, but you could use anything) to save the image to so I can actually access it. Then, just use balena etcher to flash the backup iso in the event of a failure.

Ha yes, once! I just used Balena Etcher and it worked exactly as expected.
