> While snapshot reduces file corruptions, it is not a guarantee the best I understand. The idea is that you'll only encounter corruptions that the application could already hit due to crashes or power outages (and hence hopefully supports recovering from). For example, with naive reads, you might: read the first half of the file context switch to the application application writes to the first half of the file application fsyncs previous writes application writes to the second half of the file context switch back to you read the second half of the file and end up with data in the second half of the file that the application normally only writes after it's sure that corresponding data has been written to the first half.
