My notebook syncronization

gacq.com-get

echo Receiving.....
rsync -avuze 'ssh -p 22' --delete anysyncuser@myserver:/srv/gacq/rsync/ rsync

gacq.com-put

echo Sending.....
rsync -avuze 'ssh -p 22' --delete rsync anysyncuser@myserver:/srv/gacq/

Duplicando una maquina con rsync

rsync -v -r -p -o -g -D -t -S -l -H \
--exclude /mnt/   \
--exclude /proc/ \
--exclude /tmp/ \
--exclude /home/ / /mnt/fireball/

Boot from a CD-ROM and mount the target-disk. Fix fstab and lilo.conf. Create /mnt and /proc and set the right permissions (for this directories). Then run lilo and reboot. Next time you run rsync, add these option to the command-line:

--exclude /etc/fstab \
--exclude /etc/lilo.conf \
--delete 

Backup using rsync and ssh

Host to backup (as root)

useradd -g 0 -G daemon,dip,lpadmin,shadow,sasl rbackup
passwd rbackup
su - rbackup
mkdir -p /home/rbackup/.ssh
chown -R rbackup.root /home/rbackup

Backup server (as root)

ssh-keygen -t dsa -f rhost-id_dsa
scp rhost-id_dsa.pub rbackup@rhost:.ssh/authorized_keys
# test
ssh -i rhost-id_dsa.pub rbackup@rhost

backup script

rsync -auzh \
 -e "ssh -l root -i host-id_dsa" \
 --delete \
 --include="/etc" \
 --include="/root" \
 --include="/usr/local/scripts" \
 --exclude="/*" \
 host:/ .

ssh -i host-id_dsa root@fabre.homelinux.net "/usr/bin/dpkg --get-selections" > dpkg--get-selections.txt
