#=============================================================================
# Arquivo de configuração para grub2
#=============================================================================
#
# Desenvolvido por: João Sales (joaosalless at gmail dot com)
#
# Estas configurações foram criadas no intuito de desenvolver um sistema de Backup e Recovery 100%
# automatizado de uma instalação do Windows 7.
#
# Utiliza-se o Clonezilla (versão debian) para backup e restauração de partições
# Utiliza-se variáveis como data e hora diretamente no grub.cfg para automatizar o nome dos backups.
# Está funcionando perfeitamente com algumas resalvas: Foi testado apenas em um HD interno.
#
# O HD testado tinha as seguintes partições:
# /dev/sda1 100M   NTFS (Reservado pelo sistema)
# /dev/sda2 49G NTFS (Windows)
# /dev/sda3 68G ext3 (Recovery)
# /dev/sda4   42G NTFS (Documentos) Todos os perfis de usuarios ficam nesta partição. Nenhum documento é perdido quando o Windows é restaurado.
#
# Nesta instalação utilizei:
# Clonezilla: http://colocrossing.dl.sourceforge.net/project/clonezilla/clonezilla_live_stable/2.2.2-32/clonezilla-live-2.2.2-32-i686-pae.zip
# SystemRescueCD: http://ufpr.dl.sourceforge.net/project/systemrescuecd/sysresccd-x86/4.1.0/systemrescuecd-x86-4.1.0.iso
#
# Para fazer uma instalação semelhante a esta, siga os passos supondo que a partição de Recovery será /dev/sda3:
#
# 1 - Dê boot na máquina com um LiveCD que possua o grub na versão 2.0 (eu utilizei Ubuntu 13.10)
# 2 - Use o Gparted caso precise redimensionar ou criar partições
# 3 - Monte a partição e navegue pelo terminal até a raiz da partição e crie as pastas necessárias com os comandos:
#   $ sudo mkdir -p /mnt/Recovery
#   $ sudo mount /dev/sda3 /mnt/Recovery
#   $ sudo mkdir -p {tmp,Recovery/{isos,images/{OEM,backups}}}
#   $ sudo chmod -R 770 Recovery tmp
#
# 4 - Baixe os links citados acima (Clonezilla e SystemRescueCD) com os comandos:
#   $ cd tmp
#   $ wget http://colocrossing.dl.sourceforge.net/project/clonezilla/clonezilla_live_stable/2.2.2-32/clonezilla-live-2.2.2-32-i686-pae.zip
#   $ unzip clonezilla-live-2.2.2-32-i686-pae.zip
#   $ cp -rf live/* ../Recovery/
#
#   $ wget http://ufpr.dl.sourceforge.net/project/systemrescuecd/sysresccd-x86/4.1.0/systemrescuecd-x86-4.1.0.iso
#   cp systemrescuecd-x86-4.1.0.iso ../Recovery/isos
#
# 5 - Instale o grub2 com o comando:
#   $ sudo grub-install --boot-directory=/mnt/Recovery/Recovery
#
# 6 - Copie este arquivo "grub.cfg" para /mnt/Recovery/Recovery/grub/grub.cfg
#
# 7 - Reinicie a máquina e use.
