Hi there,

I proceeded as Helene suggested

I executed gbak.
However this produced zillions of warnings of the form
gback: do not recognize table attribute 0 -- continuing

this goes on now for some 15 minutes.
A database VAS.FDB was created
I can open it from my linux box using flamerobin.
The tables seem to exist all, their structure is ok as far as I can
judge from a first glance.
But alas, they are empty!!

please advice.

robert
