[FUG-BR] Script Backup em Mail/FTP/SCP/DVDRW/CDRW

[Fabricio Lima]

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.
