Recentemente precisei criar um script de backup com algumas exig\u00eancias… n\u00e3o entrarei muito em detalhes sobre os recursos utilizados, a ideia \u00e9 compartilhar e passar um overview do que faz o script.<\/p>\n
As exig\u00eancias:<\/p>\n
As solu\u00e7\u00f5es:<\/p>\n
1. Existem algumas maneiras de obter informa\u00e7\u00f5es de um device via Udev … no meu caso utilizei o seguinte:<\/p>\n
# udevadm info –query=all –name=\/dev\/sdc<\/strong><\/p>\n Obs.: as linhas iniciadas com “P” (PATH) mostram o caminho absoluto do device, “S” (SYMLINK) links simb\u00f3licos para o device e “E” (ENVIRONMENT) vari\u00e1veis de ambiente que podemos usar nas regras do Udev.<\/p>\n Quando plugado o HDD (ACTION==”add”) com n\u00famero serial (ENV{ID_SERIAL_SHORT}==”5758323145393436444B4134″) e seja um block device (SUBSYSTEM==”block”), crie um link simb\u00f3lico em \/dev com nome BackupUSB (SYMLINK+=”BackupUSB) e execute o script RUN+=”SEU SCRIPT”.<\/p>\n 2. Tal comando encontra-se em fun\u00e7\u00e3o dentro do script, mas seguindo a ordem das exig\u00eancias … o comando \u00e9: Procura somente (-maxdepth 1) em $BKPDIR diret\u00f3rios (-type d) mas n\u00e3o o diret\u00f3rio “lost+found” (-not -name lost+found) e deleta diret\u00f3rios com 15 dias ou mais ( -ctime 15 -exec rm -rfv ‘{}’ \\; )<\/p>\n 3. O backup para servidor remoto ser\u00e1 feito via SMB\/CIFS, que nada mais \u00e9 do que uma pasta compartilhada no Windows. Para isso \u00e9 preciso instalar o pacote cifs-utils<\/em>.<\/p>\n Crie um arquivo e insira as seguintes informa\u00e7\u00f5es:<\/p>\n Teste com:<\/p>\n mount.cifs -o credentials=ArquivoComUsuarioeSenha \/\/IpServidor\/NomedoCompartilhamento \/mnt<\/p>\n Exemplo:<\/p>\n # mount.cifs -o credentials=\/root\/windows \/\/192.168.4.2\/BackupDB \/mnt\/SERVIDOR\/<\/strong><\/p>\n 4. Para envio de e-mail foi instalado o “mutt.x86_64”.<\/p>\n Crie o arquivo “\/root\/.muttrc” e insira o seguinte conte\u00fado:<\/p>\n ##REMOTE GMAIL FOLDERS ##SMTP Settings to sent email ##LOCAL FOLDERS FOR CACHED HEADERS AND CERTIFICATES ##SECURING ##Sort by newest conversation first. ##Set editor to create new email Obs.: acesse seu email via “mutt”, confirme os certificados e ap\u00f3s isso n\u00e3o ser\u00e1 mais solicitado confirma\u00e7\u00e3o. Para acessar digite “mutt” e enter.<\/p>\n Antes do script…<\/p>\n Para a montagem do HD e do compartilhamento foi instalado “autofs.x86_64” que faz a montagem sobre demanda.<\/p>\n Dentro de “\/etc\/auto.master” adicione as seguintes linhas:<\/p>\n Crie os diret\u00f3rios “\/mnt\/SERVIDOR’ e “\/mnt\/HD_EXTERNO”.<\/p>\n Crie o arquivo “\/etc\/auto.CIFS” e “\/etc\/auto.HD_EXTERNO” e adicione as linhas abaixo:<\/p>\n \/etc\/auto.CIFS:<\/p>\n \/etc\/auto.HD_EXTERNO:<\/p>\n Script para HD:<\/p>\n Script para servidor:<\/p>\n Recentemente precisei criar um script de backup com algumas exig\u00eancias… n\u00e3o entrarei muito em detalhes sobre os recursos utilizados, a ideia \u00e9 compartilhar e passar um overview do que faz o script.
