I'm currently using Deja Dup ("Ubuntu Backups") to create backups of my data. However when reading around I see a lot of issues of people being unable to restore their backups in case the catastrophe hits.
- one person reports he might have deleted his ".ssh" or ".gnupg" folder which probably contained the necessary for decrypting the backups
Obviously I want to be able to reinstall my backups whenever needed, meaning:
- my computer gets hacked and .ssh and .gnupg are deleted
- I mistakenly delete .ssh or .gnupg (might even be due to a necessary reinstallation of the operating system)
How do I prevent data loss, when the above described "catastrophe" hits? Can I note the encryption password on a piece of paper, if yes, which one?
- some .ssh key?
- some more keys? (gnupg?)
Some more infos I found around the topic "issues with restoring encrypted backups in Deja Dup":
- place Deja Dup keys / installation files in Dropbox to prevent data loss
- this guy is unable to restore the backup because of a Deja Dup software bug
