mondo rescue
ferramenta de backup para Linux sem sombra de dúvidas é o Mondo (http://www.mondorescue.org/). Gerar imagens inicializaveis completas de todo o sistema em formato ISO compactadas . Essas imagens podem ser restauradas por cd de boot ou por NFS.
Para instalar faça:
# apt-get install mondo mondo mindi mondo-doc
mondoarchive -Oi -d /home/mondo -T /home/mondo/ \
-E /root /home /var/cache /var/log /tmp /cache -9 -s 700m
Opcões:
- -Oi -> criar o backup em imagens ISO
- -d -> coloca a imagens no caminho de finido
- -T -> coloca os arquivos temporários no caminho definido
- -E -> NÃO faz backup dos diretórios e/ou arquivos definidos entre aspas
- -9 -> nível de compactacão
- -s 700m -> tamanho maximo de cada imagem
Criação de cds inicializaveis
use a ferramenta mindi
http://www.mondorescue.org/docs/mondorescue-howto.html#OVERVIEW-MINDI
# mondoarchive -OiV -p mybackup -I / -E "/media/hda1 /var/log /proc" -d /home/ravi -s 650m
The above command will create (-Oi) an ISO image containing all the files (-I) in the filesystem except (-E) the files in /media/hda1, /var/log and /proc and save the resulting ISO image in the /home/ravi (-d) folder naming (-p) the ISO mybackup-1-20.iso . And each of the resulting ISO will have a maximum size (-s) of 650 MB.
Fazendo backup via nfs
Standard Example With Network Backup
bash# mount 192.168.1.3:/home/nfs -t nfs /mnt/nfs
bash# mondoarchive -OVn 192.168.1.3:/home/nfs -g -s 200m
bash# umount /mnt/nfs
The resultant ISO's can be burned to CD's if you want (which isn't a good idea unless you're a Mondo expert because they'll try to restore over a network by default, which is silly because the archives are on the CD's). Or, you can boot from the Mindi floppies (or mondorescue.iso) and hit ENTER a few times to restore.
Those ISO images can also be used for a PXE restore. For this to work, please refer to the file README.pxe provided with your mindi package.
