This is probably result of some GUI tools (like IBExpert for instance)
that don't check fields' values, just change the field to NOT NULL.

You can use the same tools to remove NOT NULL constraint and then backup
/restore. Or you can fix records before backing up.

You wrote that it is the test gdb, so I don't see any probl.
