today, I started the usual backup with the command:

gbak -B -user SYSDBA -pas masterkey db.gdb db.bk

This time, I received the following message, which is new to me:

"done with volume #1, db.bk
press return to open that file or type a new name followed by return to
open a different file"

when I press return

"starting with volume #2, db.bk"

What does it mean ? The opguide says nothing about it.

Is gbak trying a multivolume backup ? (I don't need this).

How do I prevent this to happen ? (I am sure that at the customer's site
the message above would produce havoc) :)
