New script to take a backup of a live wordpress instance hosted
elsewhere, this takes a full copy of the web files and the mysql
database and creates a local instance of it. it also creates a tarball
of the local web directory. In my case the directory holding the
tarballs is then synchronised with an online backup service.
This script requires a config file which resides in /etc/backup and has
the .conf suffix. I will upload a sample config file.
