> at rest data shouldn't be modified If your data is kept in a SQLite database or any other type of compound storage scheme it's entirely possible to lose data that wasn't being modified, due to corruption of the metadata that governs the layout of the file (actually I don't have experience with SQLite file format specifically, but I ruined my startup's launch a decade ago with almost identical reasoning--thousands of pressed CD-ROMs in the garbage).
