Using Firebird 2.5 Superserver on a Windows 2003 server, when I attempted a full backup (level 0) restore from  a 90GB .nbk, the process aborted after about an hour, providing only "Error (1450)" as an explanation.  I don't see error number definitions in the nBackup guide.  Are they documented elsewhere?  Or might this error have actually been generated by the operating system?

Thanks,

Jonathan Finch
