Gostaria de compartilhar com vcs um script q venho utilizado ha muito tempo.. e
todo dia venho incrementando ele.
vc pode jogar no cron uma entrada pra semanalmente executar:
/usr/local/etc/backup.sh start
a diretiva start executa: compress, rotate, upload e report.
ele gera varios .tar.gz.. um pra configuracao, um pra homes, etc...
a diretiva upload estah redefinida com um OR junto com upload_ftp.. ou seja,
se digitar backup.sh upload, ele ira fazer via ftp..
se vc quer backup via email, chame explicitamente.. upload_mail...
ou entao tire do lugar q está a diretiva upload default.
lembrando q pra funcionar upload_scp vc tem q jogar as chaves publicas pra la e
pra ca, a fim de acontecer a autenticacao nao interativa
aceito comentarios.
