The sources are open, you can find them through
firebird.sourceforge.net - possibly also at www.ibphoenix.com

Several possibilities:

- At vinkenoog.nl/firebird/ I have backup-restore sources that you
can freely study, alter, or use as-is in any application.

- At www.mengoni.it/downloads.html you'll find sources and binaries
for IBOAdmin. I think these have an open source license, so I'm not
sure if you can use them for a closed source project.

- ibpp is an extensive Firebird API class library, inluding classes
for backup and restore. License is MPL. At www.ibpp.org

- And I'm sure there's more...
