Use case: I want to have a backup of my “whole” system, i.e. nearly (ideally) all config and user’s data files, so I can easily restore it in case of a failure.
What I see: I don’t need to backup the distro’s file/rpm-ostree obviously. As that can easy be restored and then likely also all packages installed.
What I don’t know:
However, how to backup the data/config files of all apps and your own personal data?
The underlying issue may be that I can hardly install any command-line (backup) tools and set them up in a cron job or so. (Or can I?)
I’d e.g. like to setup borgbackup and with the “usual” Fedora/Linux packaging model that is easily possible, as it is in the Fedora packages.
However, how are we supposed to do this, if we have a read-only distro and can otherwise only install sandboxed software (as flatpaks)?
Note I’ve only tried out Silverblue for testing and read a bit about it and have not used it extensively.
