Copy vzdump backups to FTP storage

Hello,
on my datacenter they provide me a FTP Backup account for my root server.

So my question/problem is, HOW TO get my vzdump files from proxmox 2.3 copied to my FTP site ??!!
(not need rename or delete, just copy file xyz.tar.gz from ROOT via FTP to xyz.tar.gz to my backup space)

The closest I ve found is something with curlftps, but I cant find some instructions that would help me at all ;)

PLEASE some nice description would be very nice :D

Thanks for all help
