 * Install restic > 1.14
 * Create new repository (where backups are stored)
-	* Create a new ssh keypair and share it with the remote host

+Create a new ssh keypair, in this example I'm naming the keyfile "keyfile"
+```bash
+ssh-keygen -f ~/.ssh/keyfile
+```

+Share the key it with the remote host

+```bash
+ssh-copy-id -i ~/.ssh/keyfile.pub admin@192.168.1.20

+Create a `~/.ssh/config` file and name it. In this case we will name it "remote"
+
+```toml
+# ~/.ssh/config
+Host remote
+	Hostname 192.168.1.20 # example
+	User admin
+	IdentityFile ~/.ssh/keyfile
+```

 ```bash
 # This could also be a local folder (/to/whereever/) but that's dumb.
-export RESTIC_REPOSITORY="sftp:other:/srv/repo"

 restic init
 # It will ask you for a password, ofc make this good and don't forget it.

 # Optionally add the `--tag foo` flag to tag backup snapshots
