I guess by "implementation details" you mean the fact that Brian  
mentioned that it is currenly done all in RAM.

We could, indeed do SDMF without loading it all into RAM, but I think  
that (as Brian mentioned) we'll probably implement MDMF instead!

Thank you very much for the use case.  I know that you've worked on  
such a backup system before.
