Introdução
Este documento descreve como fazer um backup do dispositivo Prime Infrastructure (PI) Gen 1 externamente com o uso de uma porta USB do dispositivo e vice-versa.
Problema
Em muitos cenários de clientes, o uso do File Transfer Protocol/Trivial File Transfer Protocol (FTP/TFTP) é restrito em seu data center e, portanto, é um grande desafio para o cliente mover o backup da PI para um ponto externo com a ajuda de qualquer servidor FTP/TFTP. Como o dispositivo é um servidor baseado em Linux, é muito difícil mover o backup de qualquer outra forma para o ponto externo porque pode haver uma possibilidade de corromper o backup no momento da transferência inadequada.
Solução
Para superar essa situação, encontre uma solução alternativa para mover o backup do Prime Server para o USB Stick com o uso da porta USB do dispositivo. Outra vantagem é que ele é muito mais rápido e ajuda a reduzir o tempo que leva para copiar por FTP/TFTP/SFTP e será muito útil copiar também grandes dados.
Backup do dispositivo PI Gen1 para USB
Etapa 1. Insira um pen drive USB.
Etapa 2. Criar um novo sistema de arquivos ext4 com suporte para a partição.
-bash-4.1# fdisk -l n e l t 8e w
-bash-4.1# partprobe
-bash-4.1# mkfs.ext4 /dev/sdb1
-bash-4.1# mkdir /media/usb-drive/
-bash-4.1# mount -t ext4 /dev/sdb1 /media/usb-drive/
-bash-4.1# umount /media/usb-drive
Etapa 3. Copie o backup de defaultRepo para o sistema de arquivos montado recentemente.
Etapa 4. Valide o md5 do arquivo em ambos os lugares.
Backup de dispositivo USB para PI Gen1
Etapa 1. Efetue login no PI.
pi/admin#
Etapa 2. Navegue até shell.
pi/admin# shell
Enter shell access password :
Starting bash shell ...
ade #
ade #
ade # sudo su -
-bash-4.1#
Etapa 3. Visualizar todas as partições de disco em PI.
-bash-4.1# fdisk -l
