This is a quick how to on backing up your Raspberry Pi SD Card

Shutdown the Raspberry Pi and remove the SD Card

Plug the SD Card into your MAC

Now the rest of the commands are done in the Terminal

Type in your password to get the # prompt

mkdir /raspberry-pi/backups and press enter
cd /raspberry-pi/backups and press enter

Type
df -h and look for your SD Card. My card is listed as /dev/disk1s1. Once you know which card is your SD Card type

diskutil unmount /dev/disk1s1 (or whatever your SD Card is listed as)

dd if=/dev/rdisk1 of=/raspberry-pi/backups/wheezy-todaysdate-backup.img bs=1m and press enter

your SD Card will now be backed up

Once the backup is complete type:
diskutil eject /dev/rdisk1

And that is it.
