	# preserve permissions, the approach below uses two commands : getfacl and setfacl
	# to save and restore permissions once your rsync is compled.
	# Alterativly, you can also explore using the fake-super options in rsync.

	# The commands below are if you have a small number of files, there are also some
	# scripts below to split up larger files in to chunks for batch processing.
