docs: explain what parts of gokrazy should be backed up

[BrunoTeixeira1996]

Platform

I’m using:

• gokrazy/rpi4b

This is more a question than a issue but I think it might be cool to update the docs with this information.
I am using gokrazy on a pi4b and that is working great but lets say I switch computers or lose the information about my pi config.
What should I do to get back the config and related files/folders?
The only option is to backup the instance folder to an external drive?

Thanks

You can use gok sbom to print all the files and directories that go into your instance’s build. The config.json is certainly most important, but as soon as you make local modifications to the software you’re installing, those locally modified program source directories become important, too.

In general, I would recommend having a daily backup for your entire machine (or at least home directory). But if you want to be more targeted, gok sbom prints all the files you need.

Another aspect to consider: the /perm partition on the Raspberry Pi. You can mirror its contents from the Pi to your PC using rsync: https://gokrazy.org/userguide/rsync-backups/

Does that make sense? I think it’s a good idea to add it to the documentation somewhere, but I’m not yet sure where the best place is.

It does makes sense!
I think the best approach here is what you said about using some type of backup.
For my case I think the best thing to do is to backup my gokrazy instance (that resides on my laptop) and the/perm partition on the Pi so then I can use the gokrazy instance folder in another pc and then copy the /perm to the pi if needed!
