innobackupex unable to backup to nfs

When trying to run:

TheSlave$ innobackupex --user=yourDBuser --password=MaGiCiGaM / --slave-info /path/to/backupdir 

The script tries to run 'cp -p' on Myisam datafiles which isn't allowed to nfs.

--stream=tar usage is required if you wish to backup to nfs mount points.
