No...  you're so far off the mark it's not even funny, especially when
it's been repeatedly pointed out to you.  This is not a file system,
it's a backup system.  It's not designed to survive a disk crash or an
accidental file deletion, it's designed to survive a direct missile
strike on your colo center.

To quote Wikipedia, "CDP is a service that captures changes to data to a
separate storage location" - emphasis on "separate".
