The solution was provided to me in the percona forum:

I did this and it worked:

ssh [email protected] "xtrabackup --user=root --password=root

  --backup --stream=xbstream --databases="uniquedb" --target-dir=./" >
  backup.xbstream 2>backup.log

This creates the backup of database named uniquedb from 192.168.0.154 to 192.168.0.109 (this is my local machine for now).
