Olá a todos!!!
Mais uma vez eu trago um script desenvolvido por mim para fazer backup de arquivos de um servidor, compactando-os e salvando-os em um ponto de montagem (de preferência de rede), ele guarda os arquivos de backup por 1 mês e então vai removendo pelo mais antigo. Originalmente esse script possuía 6 linhas (versão 1.0), mas como sempre eu me empolgo e tento fazer o mais completo possível. Eis o script:
#!/bin/bash
##########################################################################
# Script de backup 2.1 (23/05/2013)
# Desenvolvido por Rodrigo Garcia em 19/10/2012
##########################################################################
PATH=/sbin:/usr/sbin:/bin:/usr/bin
##########################################################################
# Informe os arquivos a serem copiados no campo BACKUP="" separados por espaços
##########################################################################
BACKUP=""
##########################################################################
# Informe o ponto de montagem Windows a ser utilizado no backup, ex: "//192.168.0.254/compartilhamento"
##########################################################################
MOUNT=""
##########################################################################
# Informe o username e a senha nos campos abaixo
##########################################################################
USER=""
PASSWD=""
