The plugin "Remote Backup Provider" (https://moodle.org/plugins/local_remote_backup_provider) needs a new maintainer.
This local module allows you to restore a course from a remote Moodle instance into your current instance via a REST web service. The intended use case is quick restores from an archival Moodle instance into the current yearly instance.
This plugin is currently owned by Lafayette College, but we no longer have the resources available to maintain it. We would be happy to hand it over to any responsible maintainer.
