I would recommend using sshfs and then perform these operations . How to: Mount Remote Directories using sshfs | Linuxers

I do this all the time to copy directory trees between hosts while preserving various permissions and file attributes. It is also much faster than SCP:

cd /lib/modules && tar cpzs `uname -r` | ssh user@host 'cd /lib/modules && tar xzvps'

Using the double-& forces the command to fail if I typo the directory. Of course you probably don't care about preserving access times and userids for your modules directory, but I thought it is reasonable example.

Also, I like to put the 'v' on the remote side, so when something is being extracted I know the remote site is getting it and is not just buffering in standard I/O.
