Rsync

To copy files to a remote server

rsync -e 'ssh -p 2222' *.txt username@batman:/tmp

NOTE: It might be possible to set the default ssh port in ~/.ssh/config so specifying the remote port all the time will be unnecessary.

backup dir1 to dir2 and delete missing from dir2

rsync -a --delete /media/hdd1/data-1/ /media/hdd2/data-2/

rsync with progress

rsync -av --info=progress2 root@nas01:/tmp/*Office* .
