Backup to FTP Step-By-Step to save local disk space

Right now backing up to FTP means you need to have almost 50% disk space free. That means you can never use more than half the server storage you're paying for, otherwise you'll be unable to make a backup. Especially on AWS disk space is very expensive.
The issue exists because Plesk seems to utilize just plain zip commands with file split. Why not offer an additional backup method, where e.g. all Domains are backuped step-by-step / one-by-one to FTP?
E.g.
domain1.com -> domain1.zip
domain1.zip is uploaded to FTP
domain1.zip is deleted
continue with domain2.com
Or any other way to backup to FTP without the need to have almost 50% free disk space.
