Answer: Yes.

Hint: Rsync.

You'll also probably want to look at SSH and authentication keys.

Thanks cperciva

Any other Suggestions ?

Rsync's your best bet.

If you have plenty of space on the drive you could tar the files or dd the drive and transfer using scp/ftp/sftp/whatever. This is more trouble than it's worth though. Your better off taking the time to learn rsync and using that.
