Possible unused script to remove?

Hi,

As part of my import/ export script tidy up I saw this shell script, but cannot find anywhere within this module that its called and it looks to be an early script as locations are hard coded under /home/pi etc.

https://github.com/emoncms/backup/blob/master/emoncms-copy.sh

I propose to remove the script, is this is use or can I submit a pull request to remove it?

Thanks,
Clive.
