# This script backs up stuff from my iMac to a SMB share on my PC.

# == Configuration Variables ==
# backupServer - the host name (or IP) of my PC, and the name of
#		the SMB share I set up
# backupImagePath - local folder that the SMB share will be mounted
#		to.  This is created and removed automatically.
# backupImageFile - absolute path to the disk image my backup lives
#		in (must use Disk Utility to create it first).  In this case, I
#		used the previous variable to generate the full path.
# backupVolName - This is the name of the disk image's mounted disk.
# sourcePath - Path to the root of what you want to back up (in this
#		case, my home directory).
