Once the server is configured, the setup of the SFTP repository can simply be
achieved by changing the URL scheme in the `init` command:
$ restic -r sftp://user@host//tmp/backup init
$ restic -r sftp:user@host:/tmp/backup init
enter password for new backend:
enter password again:
created restic backend f1c6108821 at sftp://user@host//tmp/backup
created restic backend f1c6108821 at sftp:user@host:/tmp/backup

Yes, that's really two slash (`/`) characters after the host name, here the
directory `/tmp/backup` on the server is meant. If you'd rather like to create
a repository in the user's home directory on the server, use the location
`sftp://user@host/foo/bar/repo`. In this case the directory is relative to the
user's home directory: `foo/bar/repo`.
You can also specify a relative (read: no slash (`/`) character at the
beginning) directory, in this case the dir is relative to the remote user's
home directory.

You can then easily initialize a repository that uses your Amazon S3 as a backend.

Please note that knowledge of your password is required to access the repository.
Losing your password means that your data is irrecoverably lost.
For an S3-compatible repository without TLS available, use the alternative URI
protocol `s3:http://server:port/bucket_name`.
Fro an s3-compatible server that is not Amazon (like Minio, see below), or is
only available via HTTP, you can specify the URL to the server like this:
`s3:http://server:port/bucket_name`.
