Home Backup Script (Python)

Como prometi, venho aqui colocar uma nova aplicação.
Na altura precisava de algo que me fizesse um backup da homedir e uploadasse para um servidor o backup pus-me ao trabalho de fazer um script que o fizesse.

Consegui chegar à versão 0.3 desse script e comecei a fazer uma 0.4, quem sabe se daqui a uns tempos não continuo a 0.4

Ah e este script até faz logs e utiliza um ficheiro para as configurações :-P
