Suppressing database triggers (Firebird 2.1+)
Firebird 2.1 introduced the concept of database triggers.Certain types of these triggers can fire upon making or breaking a database connection.As part of the backup process, nbackup opens a regular connection to the database (in some versions even more than once).To prevent database triggers from firing inadvertently, the -T
or — since Firebird 3.0 — -NODBTRIGGERS
switch can be used.
