ZFS Send/Receive - Low transfer rate

Post by MauroRS »

Hi guys,
I need a help with a problem. I tried to use the send/receive to backup my N4F data with a bad result. I have a N4FServer and a BkpServer and I tried to use the send/receive with ssh, but the transfer rate was really slow (50kb/s). My bkp full has 6GB and with this transfer rate is impossible to work.

zfs send -Rv testpool@Base ssh root@xx.xxx.xxx.203 zfs recv -dvF zfsbkp/testpool

Can Someone help me with this problem?
