After watching better linux youtubers go through this process, I modified it to fit my needs and did this exact set up on my laptop.
Replicated here for you to take a look.

Switched from Manjaro to:
Debian Testing
Cinnamon
Btrfs
Timeshift

Also installed nala
sudo apt install nala (debian testing only)

Mit dem für Linux Mint entwickelten Tool Timeshift erstellen Sie einfach System-Snapshots, verwalten sie und spielen sie bei Bedarf wieder zurück.

Die Datensicherung betrachten bekanntermaßen viele Anwender als notwendiges, aber recht lästiges Übel. Idealerweise gestaltet man das Backup also so, dass man sich nur einmal Gedanken darüber machen muss: beim Erarbeiten einer Strategie, bei der die Software der Wahl künftig ohne weiteres Zutun diesen Job übernimmt.

Timeshift protects your system by taking incremental snapshots of the file system at regular intervals. These snapshots can be restored at a later date to undo all changes to the system

The Btrfs filesystem-level encryption feature is still not available. But you can use a 3rd party encryption tool like dm-crypt to encrypt the entire storage devices of your Btrfs filesystem.

In this article, I am going to show you how to encrypt the storage devices added to a Btrfs filesystem with dm-crypt. So, let’s get started.
