Reliability is critical for most embedded systems and devices. So when a power loss or crash occurs, it is important that files do not become corrupted. By default, many operating systems do not protect against such corruption. However, by selecting the correct file system and incorporating a database library into applications, it is possible to protect data from crashes.

This white paper describes the various ways that data can be lost and shows how different file systems can be used to improve reliability.
