> does IBO V4.2 provide any backup/restore functionality ?

There is an alternative program (developed by me and based
on the IB_Extract code included in IBO) available at:
http://www.telesiscomputing.com.au/dbk.htm

Source code available for the Delphi components, fee required
for commercial use (trustware licence like IBO). See the
above page for details. Its quite different to gbak so be
sure to try the free prebuilt executables (and read the
associated help file) before deciding to use this utility in
a production environment.
