I am not sure what you mean by data integrity.
In short, when Cassandra starts up it searches it's data directories
and loads up the data, index, bloom filters, and saved caches it
finds.
Unless the files are corrupt it will happily load up what it finds.
Restores are done by the process your described , stop server, restore
files, start server.
