Mac: moving large amount of files off to external drive

I have tried to clean up my hard drive in preparation to upgrade to SSD. Moving files using Finder FAILS all the time an in the end you don't know what was copied and what was not.

I used rsynch tool because it it smart enough to copy ONLY new and changed files, so I can run it multiple times and transfer only the differences (delta).

$ sudo rsync -varpog --progress ~/Documents/SourceDir/ /Volumes/1TB_BU/DestinationDir/  Password:building file list ... 8943 files to consider.DS_Store      159748 100%  121.10MB/s    0:00:00 (xfer#1, to-check=8941/8943)2013-08-15 09.35.24.mp4    87290465 100%   22.57MB/s    0:00:03 (xfer#2, to-check=7445/8943)2013-08-15 11.51.18.jpg

Consecutive runs:

Options:

-h show full help

-v verbose
--progress show progress while transfer
-h unman readable
-q quiet for non-error
-r recursive
-a archive
-b backup
-p preserve permissions
-o preserve owner
-g preserve group
-z compress data during the transfer

My favorite quotations..


“A man should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.”  by Robert A. Heinlein
