The 'Backup file' option requires that he had saved once as a SEQ file, which apparently he didn't (since it is not the default and often misunderstood).

As far as the which is better argument goes; if RB saves as a SEQ file natively your BiaB is not totally lost .. even if you had done work on it. Open the SEQ file in RB and Save As a sgu .. whatever info RB has that CAN be put into sgu will be.
If it can't save certain data, I don't think you could have saved it back to BiaB in the first place.

There is really only one way data can be 'totally lost' here and that is when SEQ is not the default.
If I save a BB file as an SEQ file in RB I have a lot better chance of salvaging the SGU later (from the SEQ) than ever recovering the SEQ (from the sgu) file if it goes the other way.

/edit
Why would you ever want to go back to BiaB after moving things to RB?
that's a really rare occasion here
