Thanks for the discussion here. I wanted to just clarify - we take data integrity very seriously and actually checksum EVERYTHING. We assume that data might get mangled over the Internet, in memory, on disk, etc. Thus, we checksum each file on your computer and ensure that it is returned to you upon restore identically. Our system also does self-healing: monitoring every file in the datacenter and if a checksum ever doesn't match (due to a cosmic ray flipping a bit on a harddrive), it automatically contacts your computer to request that bit of a file be backed up again.
