Yep, sorry for that.

Sure, GBAK is just a client application that is firing requests at
the server. At index restoration time, the server is looking for a
file that it needs to read from (or write to) for some part of the
index-building operation and, for some reason, it is receiving a
blank file name. If it knew what file it was looking for, there
would be a filespec between the double quotes, instead of a space character.

Now that you mention it is Superserver you have installed on the
Windows machines, the next obvious question to ask is which model you
have installed on the Posix machine and what syntax you are using
there for invoking gbak. Could you give it exactly, please?

It has to read and write indexes when performing DML.
