I want to copy 60 GB from server to another server.
So I will need use both commands. I need the best and the easiest command to do this with good explanation.

Much appreciated!

Ok..so read the man pages on both the tar and scp commands. That will give you your good explanation. Also, rsync can use SSH, and handle compression, so the man page there will also give you an explanation.

If you read the man page on SCP, pay particular attention to the "-C" option...which does compression BEFORE sending, and omits the need for using tar at all. A small bit of research can help you answer your own questions.

There are also THOUSANDS of easily-found hits in Google for "linux tar output into scp", with examples. Did you try to look? For example:

Thanks for the help. I was just want to this backup ASAP, so didn't try to google it
Anyway thanks!

I'm now using;
tar czfv - file | ssh root@dest tar xvzf - - C dest dir

it's taking much time!

they are 60 GB

So instead of trying to look anything up when you're in a hurry, you post it here, and expect others to do it for you, and post back? Not only does it take more time, but is a bit lazy.
...and what's surprising about that?? 60GB's transferring over the network WILL take time.

no problem thx
