During restore from a backup, I get this error:

------------------------------------------------------------
SQL Message : -902
Unsuccessful execution caused by a system error that precludes
successful execution of subsequent statements

Engine Code : 335544373
Engine Message :
operating system directive WriteFile failed
There is not enough space on the disk.
------------------------------------------------------------

How can I determine which disk needs more free space?
Is there any way I can reduce disk space requirements for the restore
operation?

I have over 40 Gbyte free on the OS disk C: and 120 Gbyte free on the
database disk D:. The pre-backup database is ~75 Gbyte.

The error occurs on this operation, according to log: "activating and
creating deferred index UppgiftshållareUnika", which is a unique
constraint on two columns, bigint + varchar(50). Charset UTF-8.

Firebird 2.1.4.18393 64 bit on Windows Server 2008 64 bit.

Regards,
Kjell
