Use xtrabackup to create full+incremental backups and send it to another host

I have checked documentation and part related to sending backups to another host is only in innobackupex tool description. (I know that innobackupex is a wrapper for xtrabackup but I need to use xtrabackup)

I need to use xtrabackup to perform full backup on some node and then send this full backup to backup_host.
How to achieve it? It is possible with xtrabackup not innobackupex?

Already I’m creating full backup using:

xtrabackup --backup --target-dir=/data/backups/base
then incremental:

xtrabackup --backup --target-dir=/data/backups/inc1 --incremental-basedir=/data/backups/base

What should I add to send those backups during xtrabackup running to another host?
