REST Server

In order to backup data to the remote server via HTTP or HTTPS protocol, you must first set up a remote REST server instance. Once the server is configured, accessing it is achieved by changing the URL scheme like this:

rustic -r rest:http://host:8000/ init

Depending on your REST server setup, you can use HTTPS protocol, password protection, multiple repositories or any combination of those features. The TCP/IP port is also configurable. Here are some more examples:

rustic -r rest:https://host:8000/ init
rustic -r rest:https://user:pass@host:8000/ init
rustic -r rest:https://user:pass@host:8000/my_backup_repo/ init

If you use TLS, rustic will use the system’s CA certificates to verify the server certificate. When the verification fails, rustic refuses to proceed and exits with an error. If you have your own self-signed certificate, or a custom CA certificate should be used for verification, you can pass rustic the certificate filename via the --cacert option. It will then verify that the server’s certificate is contained in the file passed to this option, or signed by a CA certificate in the file. In this case, the system CA certificates are not considered at all.

REST server uses exactly the same directory structure as local backend, so you should be able to access it both locally and via HTTP, even simultaneously.
