Dmitry,
 
Yes, the problem seems incredible. If I heard it from someone else, I would also have difficult to believe on that. But this is as it is !
 
I will not repeat (ooops, I am already in the way !) that the source DB (for the backup) is ok. And the backup, as only could be, really has the problem. And the backup was generated not by a rocket, but only by the GBak ! This mean = or the problem happens at the backup process, or during the restore process. But as we have no tool to see the backup content, it´s not possible to know where, in these two steps, the problem happens.
 
We experimented to restore first only the DB structure and then restore the data, and then we got no error. Using the same backup file.
  
 
 
We have FB 2.1.

Hello, Tupy...!

The funny thing is that gbak is not a rocket sience, it simply does
select * from table and writes the data to the backup file.
So, if you have problem, the source is in the database or in the
backup.

I also do not see what Firebird version do you use.

p.s. please, do not overquote.
