Subject Backup in embedded mode using C API - authentication problem
Author Bunth Tamás

I want to make a backup (.fbk) from a local database (.fdb). As far as I know,
I shouldn't pass username/password in the spb to isc_service_attach() in embedded mode. However,
I got an error during retrieving information with isc_service_query:

*Unable to perform operation.  You must be either SYSDBA or owner of the database
*Exiting before completion due to errors
caused by

So is it possible to backup a database in embedded mode?

Thank you,
