Of the four examples you give, three render the backup useless
because of the DRM system. The fourth renders the backup useless
because the backup was destroyed.
Off-site backups can solve the problem in your fourth example. Nothing the user can do can fix the problems of the first three.
It seems clear to me that it's the DRM rendering the backup data useless, if the user cannot take any steps to avoid the data becoming useless if certain events occur.
