Final situation is:

- The guy who did back up didn't say that back up from friday didn't
finish sucsefully
- On saturday, they worked OK (this is strange, when first problem
occured on friday. WHY IT WAS POSSIBLE TO WORK ON SATURDAY, WHEN
PROBLEM OCCURED ON FRIDAY!!! I gues we will never know).
- On saturday, back up wasn't possible
- Today, database is dead.

I will solve current situation somehow, but for the future, and for
other people, it would be good that somone who is familiar with these
things explain such behaviour.

My expierence with IB is 5+ years long.
HDD's on Server are relativelyu new (less than 1 year). We have 2
discs with 80GB capacity both of them.

Thanks to all who tried to help. For me, case is finished (except I
am still retyping invoices from Saturday, :) ).

Regards

Zile
