If the errors are located in a specific index (or unique constraint),
would it be a good idea to drop that index/constraint and try a regular
gbak backup/restore cycle?

And if the errors are located in a table's data pages - drop the table
and do gbak backup/restore?

I did get an indication that it might be in a table I can recreate by
other means...
