You can't mix 32 and 64-bit Firebird processes accessing the same physical database, so e.g. under Firebird 2.5, you can't access your database with a 32-bit Firebird Embedded client while it's in use by a regular regular Firebird 64-bit server process.

Sure, a backup/restore cycle never hurts, but I haven't encountered problems so far when simply copying a physical database file for Firebird 32/64-bit access.
