You can transfer the incremental backup archive to the live server's root yourself e.g. by SFTP or FTP. Then there are two options:
1. Go to Akeeba Backup, Import and point it to your newly uploaded backup archive. Then go to Manage Backups, select the imported archive and click on Restore in the toolbar.
2. Upload kickstart.php (from Akeeba Kickstart Core) and access it with a browser to restore the backup archive you uploaded.
The second option is typically easier since you're already uploading the archive by (S)FTP.
