What about a catastrophic event that wipes out millions of nodes

FYI,
Did some quick off-forum reading/scanning the other day and noticed that “map of datamaps” is mentioned as a means of versioning files in SAFE. Not sure if it has been implemented this way, but your idea may already exist in the code to some extent… not sure.

I have a feeling this capability is built into safe_nfs

It was certainly in the data structures for the proposed implementation back in the old days (C++ you know, is sso last century ).

EFIT: Actually, I take that back - my guess is this is built into the datamaps layer already. All you need is a pointer back to the previous datamap version.
