rbootx is a small bash script that creates bootable backups for OS X,
using rsync.
Note that rbootx requires the latest rsync
from Homebrew.
# the only required arguments are a source and a destination
rbootx / /Volumes/Backup
# dry run
rbootx -n / /Volumes/Backup
# supress the (minimal) non-error messages
rbootx -q / /Volumes/Backup
