File transfer

Transfer files between servers

scp

scp — OpenSSH secure file copy

rsync

rsync - a fast, versatile, remote (and local) file-copying tool

It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination.

# sync current dir to remote dir
rsync -avz . ubuntu@raspberrypi-live:~/work
# sync remote dir to current dir
rsync -avz ubuntu@raspberrypi-live:~/work .
