The single file bit-by-bit replication is only possible if those bits still exist and you have guarantees of it. Those bits are a hidden dependency unless you mirror them. Without a mirror it seems like replication will work most of the time, but will eventually fail in ways you don't want.
I mean I could but I find a full drive backup isn’t that much bigger than a more selective backup and whenever I try to back up part of a drive I never grab the right bits.
I think the point was a single file for bit by bit replication. Managing infrastructure isn't good ROI here.
