A better option may be an MD5 comparison of the contents of the files. If you're going to go through the trouble of creating a rollback mechanism for copying, you should at least verify that the files are exact matches (well, MD5 has a slight chance of creating the same hash for slightly differing inputs (i.e. the hard drive misreads and puts "I am a lonely man" instead of "I like to dress in women's clothing" and you get the same MD5 for both lines...which you don't, I checked), but the chances are somewhere in the realm of winning the lottery every drawing during a year and then dying from the combination of a shark attack and simultaneously getting struck by lightning, all while in Kansas...driving on the highway...in the middle of winter.... Actually, on second thought your chances may be worse than that...).
