Databases use journaling to avoid these issues. The difference between RDBMS' journaling and file system's journaling is the RDBMS journals application data, the file system does not (with few exceptions). Thus, a RDBMS gives you consistent application state, while the file system does not (with fewer exceptions, basically only TxF). Another pain point is backup; it's not possible to create a consistent snapshot of (rdbms state, other state on the file system). This is avoided entirely if you only need to snapshot (rdbms state,).
