FBClone can clone a http://www.firebirdsql.org database in one shot (instead of backup/restore cycle) and pump data from one database to another with the same structure, it handles metadata / data charset conversion and may be useful to ease database owner change process or to migrate a database between two different firebird versions (eg. 2.1 -> 1.5)
Latest version have flags to ignore charset definitions from source database metadata so you can "normalize" a database with multiple charsets to only one, for instance, UTF8 (see -ics and -ko flags in conjunction to -tc UTF8)
