A system compromised of hardware and software elements and practices
is needed which will provide 100 per cent reliability.
That means the system will be used to store backup data.
The system is expected, required to always provide healthy data stored on it.
That means it will never occur that the system can’t provide healthy
That means for instance if some day data gets corrupted due to
errors in file system or bad sectors or similar the system must be able
to recover from it. System must be also able to detect possible problems
which can lead in lose of data stored on it and enter appropriate measures
of maintainance to avoid data damage.
How have such a system look, what elements must be included?
I talk about hardware, software, methodics, practicies others.
Let’s use a NAS and additional external data storage as starting point
