Today you can verify backups on OS X with "tmutil verifychecksums", at least on 10.11. The UI to this could be improved, but user data checksums don't necessarily need to be a filesystem feature. On a single-disk device, the FS doesn't have enough information to do anything useful about corrupt files anyway. |

Some filesystems can be configured to keep two or more copies of certain filesystem/directory/etc. contents. Two copies is enough information to do something useful.
