Use feature branch for package sftp

Currently, filepath.Join is used to join path fragments that are supposed
to be created on remote storage backends. This could theoretically cause
problems when the separators used by the client and the remotes do not match.
It's unlikely this causes problems right now, but it's definitely better to
rectify it before it causes further confusion.

This was raised in #541

+
+## Using GPG encryption
+
+In case a `GPG_PASSPHRASE` or `GPG_PUBLIC_KEY_RING` environment variable is set, the backup archive will be encrypted using the given key and saved as a `.gpg` file instead.

+
+## Using age encryption
+
+{: .note }
+Even though the `age` CLI tools supports encryption using SSH keys, this is not supported by this tool.
+`AGE_PUBLIC_KEYS` currently expects `age` keys to be given.
+
+age allows backups to be encrypted with either a symmetric key (password) or a public key. One of those options are available for use.
+
+Given `AGE_PASSPHRASE` being provided, the backup archive will be encrypted with the passphrase and saved as a `.age` file instead. Refer to age documentation for how to properly decrypt.
+
+Given `AGE_PUBLIC_KEYS` being provided (allowing multiple by separating each public key with `,`), the backup archive will be encrypted with the provided public keys. It will also result in the archive being saved as a `.age` file.
