I am having the same problem.
How can I download the restore script from my new host when xcloner is not installed on the new host? I wanted to restore the backup without installing a new version of wordpress first.
I understand that a remote restore can be done from the original site, but I want to be able to restore from a remotely saved backup in case I want to move the site to a new server or the old server is not available for a remote restore.
I also do a lot of cloning of sites from my local server to a production server and vice versa, so the local server is not available for a remote restore from the original server.
Hopefully you can understand what I would like to do.
