> I read the documentation of FBCopy/FBExport and it seems that only transfer data not metadata (tables structure, triggers, etc), and I would like to synchronize also the whole database, including the structure.

But you must have original database create script. It is basic of DB
development - always keep script of clean database creation.
If you are not clever enough to keep original script, you can use any
tool able to extract metadata to scrips: FalmeRobin, IBExpert or isql.
