I’ve been running #octoprint since 2016, and I maybe flashed a new version of OctoPi once since then, perhaps when I got my Prusa in 2019.
I finally needed to reflash the OS to upgrade my Python installation. That meant I actually used the Backup plugin for the first time yesterday to download all of my settings and data. However, that file was 1.4GB, which is too large to restore using the plugin. (No timelapses even!)
So, thanks to excellent instructions written by @foosel in 2018, it was super easy for me to use SCP to upload the file directly to my poor, slow, Pi2, and then run the restore function via SSH to get everything back to normal.
I honestly avoid the command line as much as I can. So, I’m grateful for well documented FOSS projects like OctoPrint that help me when I have to do it the hard way.
