First "trust Amazon."
Second, mainly when I speak of backing up, I think of those things out "in the wind" not supported by third parties. My notes. My References. My books, articles.
Third. Before eReaders became so pervasive, I had many other files from various places that never had DRM. And of course I have many used books that I got for nominal sums $4.00 or so that I use as reference.
Fourth. The DRM I support is to protect me from you. Not so much you from me.
Fifth. Any DRM can be beat. I know this. I also know that most readers will not bother. The problem is when the people that beat DRM then put the open files out for pirating. That is my worry.
