Backups people backups. You don't realize how much you want them until it's too late to make them.
- don't worry I have raid, that's a backup right?
  
  Raid 0 right? I heard the number stands for how much risk there is of losing data.
  
  Add more disks for more reliability
  
  Due to the green economy I only buy second or third hand disks for my RAID0 setup
  
  No, the backup goes after the raid when something goes wrong.
  Wait, I thought you're talking about that SWAT team outside your house.
  
  If 3-2-1 is a good backup strategy, RAID (non-zero) is like 0.5 at best. Maybe 0.6 if your config can handle 2 simultaneous drive failures
- How do I make a backup of my pi and all its settings? I set everything up following guides and am not great with Linux. Is there a way to make like a full clone, so I can just copy paste into a new pi in case?

  This tool is incredible
  
  Yeah, I think the same software you used to image your SD card can be used to make an image from your SD card.
  
  Copy the entire SD card (both partitions) with a tool like dd to a file.
- Also remember to backup before things break. I once diligently backed up a system image before an upgrade. But I backed up a already failed SD card.
  
  Also remember to test your backup system.
  Setting up an intricate backup process is great, until an actual emergency happens and it turns out you can't put Humpty-Dumpty back together
- and if possible, keep some backups in a separate physical location. House fires or break-ins aren't all that uncommon.
  
  A good advice, but most regular people don't seem to bother with rotating physical off-site storage mediums so I advocate automated (and encrypted) backups to a cloud or something as well.
