That's not quite right. Dump knows as much about the file system
structure as the kernel does. For instance, it backs up one file at
a time.
What it does not do is use the normal OS interfaces (open/read/close)
to access those files. Instead, it parses the file system structures
to find the actual disk blocks involved and reads them directly.
The (theoretical) advantage to this is performance. Dump does a lot of
things in parallel and knows its exact usage pattern.
It also does not affect any file system metadata (such as access time).
