I sirt it manually. I just rip a CD, edit its metadata with MusicBrainz Picard then place all the MP3's in a folder for just the book and then move it to the folder of the author.
Once scanned by audiobookshelf I modify the metadata a bit more and then let audiobookshelf combine the book to one file.
I use the integrated /e/OS backup which is actually Seedvault which runs great :). But you need a service to store you backups, WebDAV, SMB or etc. Neo Backup (which I have used for many years on Lineage OS) seems to be able to make backups to a SD card.
/e/OS it is degoogled but most of the "Google" applications have been replacedby great opensource alternatives or adapted. The app store still allows us to install apps from the playstore but anonymously.
I use duplicacy to backup to my local NAS and to Storj.io. In case of a fire I'm always able to restore my files. Storj.io is cheap, easy to access from any location and your files are stored and duplicated on multiple different locations.
I have used duplicity before but restoring from a new installation takes a while, as duplicity has to reanalyze the storage.
What a journalistical mistake, you can't directly compare a group of countries with a single country. In this case fallen behind means in money. Which is quite a bad assumption.
Well, Windows isn't that popular in the computer scene. Linux is by far more popular for servers, IoT devices (payment terminals, heartrate monitors...) and critical systems. But Windows has an edge in the PC scene. But to be honest a Apple Mac is also in the formfactor PC. These charts are always way of, just because their definition and monitoring techniques are not trustworthy.
The problem with Linux: it is opensource and free, and everyone can rebrand it. But at the same time everyone wants to make a euro out of it. There are a lot of companies that misuse its license by closing the source.

Contabo and NetCup are really cheap. But only if you use their shared VPS option. If you are lucky the CPU steal is low.
