Backup da Área Web e Home

Description

Para fazer o backup da área web utilizamos a fita dat e o crontab. O backup esta agendado para todo dia as 02h da manhã. Incluimos no crontab:

 
[root@sprace ~]# crontab -e
00 02 * * 1-7   /bin/tar -cjvpf /dev/st0  /export/html /etc /var/www  /export/home > /dev/null 2> /root/backup.log
 
Isso irá escrever um log no /root/backup.log. Para visualizar o backup use
tar -tjvf /dev/st0

Updates

O crontab foi modificado: semanalmente (domingo) fazemos um backup full em disco (/disk1/backup-full-data_do_dia.tar.bz2), removendo o anterior para salvar espaco. Diariamente as 02h fazemos um incremental.
 
00 04 * * 1  rm /disk1/backup-full-*.tar.bz2;/bin/tar -cjvpf /disk1/backup-full-`date +DONEm%d`.tar.bz2  /export/html /etc /var/www  /export/home
00 02 * * 1-7 mt -f  /dev/st0 rewind; /bin/tar -cjvpf /dev/st0 --label="incremental-backup created on `date '+%d-%B-%Y'`." -N `date`   /export/html /etc /var/www  /export/home > /dev/null 2> /root/backup.log
 

Updates

Devido a um erro nas aspas coloquei tudo em scripts no /root/backup. Ainda foi colocada a opcao i no tar para ignorar os EOF
[root@sprace backup]# crontab -e
00 04 * * 1  /root/backup/backup_semanal.sh
00 02 * * 1-7 /root/backup/backup_diario.sh 
[root@sprace backup]# more backup_diario.sh
#!/bin/bash
mt -f  /dev/st0 rewind; /bin/tar -icjvpf /dev/st0  -N `date +DONEm%d`   /export/html /etc /var/www  /export/home/novaes > /dev/null 2> /root/backup/backup.log
[root@sprace backup]# more backup_semanal.sh
#!/bin/bash
rm /disk1/backup-full*.tar.bz2;/bin/tar -icjvpf /disk1/backup-full`date +DONEm%d`.tar.bz2  /export/html /etc /var/www  /export/home /OSG ; cd /raid0/sprace_backup;rm -rf /raid0/sprace_backup/semana1;mv /raid0/sprace_backup/semana2 /raid0/sprace_backup/semana1;mv /raid0/sprace_backup/semana3 /raid0/sprace_backup/semana2;cp -al /raid0/sprace_backup/semana4 /raid0/sprace_backup/semana3;rsync -avz --delete  /export/html /raid0/sprace_backup/semana4/;rsync -avz  /etc /raid0/sprace_backup/semana4/;rsync -avz --delete /var/www /raid0/sprace_backup/semana4/;rsync -avz  --delete /export/home /raid0/sprace_backup/semana4/;rsync -avz --delete  /OSG /raid0/sprace_backup/semana4/;

O backup é rodado no em /raid0/sprace_backup, o mais velho em semana1, feito usando o rsync.

Atualização 02/06/2008

O backup passa a ser dirigido não para o /raid0 e sim para a evo.sprace.org.br. Esta maquina aceita somente autenticação por chaves, desabilitando a autenticação por senha.
#!/bin/bash
mount /OSG; ssh evo.sprace.org.br 'cd /scratch/sprace_backup;rm -rf /scratch/sprace_backup/semana1;mv /scratch/sprace_backup/semana2 /scratch/sprace_b
ackup/semana1;mv /scratch/sprace_backup/semana3 /scratch/sprace_backup/semana2;cp -al /scratch/sprace_backup/semana4 /scratch/sprace_backup/semana3';r
sync -avz --delete  /export/html evo.sprace.org.br:/scratch/sprace_backup/semana4/;rsync -avz  /etc evo.sprace.org.br:/scratch/sprace_backup/semana4/;
rsync -avz --delete /var/www evo.sprace.org.br:/scratch/sprace_backup/semana4/;rsync -avz  --delete /export/home evo.sprace.org.br:/scratch/sprace_bac
kup/semana4/;rsync -avz --delete  /OSG evo.sprace.org.br:/scratch/sprace_backup/semana4/;umount /OSG

Atualização 26/10/2008

Para os backups do /OSG estamos usando um disco montado via nfs da access:

cd /root/backup/
vim backup_diario.sh
==============
montado=`df -h | grep /hdacs`
if [ -z "$montado" ]; then
echo "Diretorio nao montado"
exit 1
else
rsync -av --delete /opt/osg-1.0.0 /hdacs/BCKP/OSG/
rsync -avz -e "ssh -i /home/mdias/.ssh/id_rsa -l mdias" osgse:/opt/d-cache /hdacs/BCKP/dCache/
rsync -av --delete /etc /hdacs/BCKP/etc-osgce/
fi
==============
chmod +x backup_diario.sh
mkdir /hdacs/BCKP/OSG
mkdir /hdacs/BCKP/dCache
mkdir /hdacs/BCKP/etc-osgce
mkdir /hdacs/BCKP/certificados
crontab -e
00 02 * * 1-7 /root/backup/backup_diario.sh
su - mdias
ssh-keygen -t rsa
#na osg-ce
vim .ssh/authorized_keys
#copie o conteudo de .ssh/id_rsa.pub da osg-ce lá

os outros backups ainda não foram implementados (/home da spweb e área web)
