One way to copy files to and from a machine is as follows:

To copy from the machine you are on

tar czf - dir1 dir2 dir3 | ssh "tar xzf - -C path/for/new/files "

To copy from a remote machine to the machine you are on

ssh "cd path/to/dir/you/want ; tar czf - diryouwant1 diryouwant2 " | tar xzf - -C where/it/goes/locally

This has advantages that it does not copy symbolic links. It also compresses the data while copying


ssh "cd path/to/dir/you/want ; tar czf - diryouwant1 diryouwant2 " > where/it/goes/locally/file.tar.gz

This will compress the data, copy it, and keep the data as a compressed file.

Another (better) way to copy files is by using rsync and screen. I am going to use a scenario, say I am going to copy my home to another server.

On my desktop:

 screen -dR my_home

Note that my_home could be anything, it's just the name of the screen. Then to copy my files:

 rsync -arv /home/jill/* someServer:/home/jill/

Then to detach from the screen:

 Hold ctrl+A, let go and then type d

You should now be detached from the screen.

To see a list of your screens type:

 screen -ls

To reattach to my screen:

 screen -r my_home
