Backing up keys
What's the best option for ssh key and mfa code backup? Right now my keys are "stored" in my downloads folder 😅 and I'm trying to get a handle on my digital life.
I have a NAS that holds all of my data and configs, which I encrypt and then backup to the cloud using using restic.
Can I just throw a copy of my keys on my NAS, and let them get backed up to the cloud? I understand that using something like BitWarden is probably "preferred", but my understanding is that doesn't actually change how keys are stored: You have a local copy and an encrypted cloud copy.
If just I put a copy of my keys in an encrypted backup, am I exposing myself to any additional risk?
My encryption keys for the cloud backup are printed out and will be stored at a second location.
Thanks in advance.
