dd is usually not a good way to back things up because of speed. "dd if=/dev/mapper/vg-home of=/dev/disk/by-id/usb-123456 bs=1M" would take 90 minutes every time it ran because it's transferring 300ishG. "rsync -av --delete-after /home/ /mnt/backup1/home/" usually takes 2-5 minutes because it's only transferring the files that have changed, which is usually 150-500M or so.<br>
