Running cpbackup_transporter directly

Hi

Last night my backups failed with a transport error, but it looks like the backups completed first. I want to try and run the transport routine separately, as it was the last day of the month and I usually keep these for a while. I found a thread here which said I could run
/usr/local/cpanel/bin/cpbackup_transporter directly, but this reports there is nothing in the queue and exits. However, when I check my remote location, I can clearly see it is missing several accounts.

How can I force the cpbackup_transporter to go do it's thing and fix my remote copies ?

 

I was kinda thinking someone would tell me to do that, but I didn't want to perform a full backup during the day. The backups are all sitting nicely in the /backup folder on the server, just need them going to my remote destination.
