Let me phrase my question another way:

If I have a good backup DBC (i.e., mydata.DBC, mydata.DCX, mydata.DCT files) can I copy them over top of a corrupt production DBC without losing associations with the production data tables?

The backup DBC is a day-old backup of the production DBC that has gotten corrupted. (No table structures, fields, or indexes have been added or modified since the backup.)

I have my data folder backed up. I just want to know if the backup DBC will be OK to use in this way even if though is not the current one, but a replica.

Thanks,

-Steve
