If you are going to make a number of changes or just want to backup your own home directory as needed, I came across this utility (GPL) to do it. While it can be modified to do different types of backups, in its simpliest form, you run it and it creates a backup "snapshot" of your directory. Works great: http://www.fourmilab.ch/webtools/flashback/
I put the code here in case it should disappear. Please DOWNLOAD it from the link to ensure you have the most recent copy.
Also, do your sysadmin a favor, and do not backup things that get caught in the normal backup.
