# Rsync based backup for Mac.

# Usage: bk ~/path/to/backup/
# E.g. bk ~/Documents/Audio will create /Volumes/AhmadAwais.com/Z-BACKUPS/Users/Documents/Audio backup.
function bk() {

	set -e
	echo "-"

	#  -a is archive mode so it keeps your original created and modified properties.
	#  -v is verbose mode to get a bit of extra output (useful for debugging).
	#  -R is relative mode. It ensures the included paths get created on the target.
