it may very well have worked that way. Unfortunately, that's not a good
outcome. If the missing file is out of date compared to the other files in
the last backup, then that may introduce subtle errors. It depends on what
edits occurred after that.

So, for example, any relationships after the next-to-last backup you added
will be missing. Worse, citations you added to the missing relationships are
sitting in the citations table and are orphaned. If you start to add the
citations back in, the citations could be reattached, but not necessarily to
the same relationships as when you added them.

Cut your losses. One day of data entry is not that much to lose, and
worrying that you've introduced errors into the project is worse than
repeating the data entry.

You did it already. You tried to use the most recent backup and it failed.
That's the test that matters.

I don't know, and that's partly why I am interested to hear what Jim has to
