The problem with xtrabackup. Error writing file 'UNOPENED' (Errcode: 32 - Broken pipe)

Hello.I use this command for copy mysql data to a slave server:innobackupex --stream=tar ./ | pigz -p 4 | pv > /dev/tcp/10.10.1.40/4444
On the slave server i use:
nc -l 4444 | tar -zxv
But i get the error:>> log scanned up to (193253267572108)                                                                                                                                 ]

I think, your TAR-command is not corect. try these one:nc -l 4444 | tar xzvf -
