My whole infrastructure is designed so that my homeserver is expendable.

Therefore my most important tool is Syncthing. It is decentral, which is awesome for uptime and reducing dependance on a single point of failure. My server is configured as the “introducer” node for convenience.

I try to find file-based applications, such as KeePassXC or Obsidian, whenever I can so that I can sync as much as possible with Syncthing.

Therefore there is (luckily) not much left to host and all of it is less critical:

• Nextcloud AIO: calendar, contacts, RSS, Syncthing files via external storage
• Webserver: Firefox search plugins (Why is this necessary, Mozilla?!), custom uBlock Origin filter list, personal website

So the worst thing that can happen when my server fails is: I need to import my OPML to a cloud provider and I loose syncing for some less important stuff and my homepage is not accessible.

Since I just rebuilt my server, I can confirm that I managed a whole week without it just fine. Thank you very much, Syncthing!
