backup Span<byte>

A span to fill will the data which was already present, or an empty span.

Remarks

backup may be an empty span. When it is, no backup is made.

targetKind is to be used as nothing more than a hint. The system should check the existing mapping to ensure that it is in fact correct (so that it would not remap an RW page to an RX page, or something similar).
