Subject GBak -Restore Error
Author Michael Vilhelmsen

I have a Backup of a DB, which gives me this error upon restore:

Invalid insert or update value(s): object columns are
constrained - no 2 table rows can have duplicate column values.
attempt to store duplicate value (visible to active transactions) in
unique index "RDB$PRIMARY19".

AFAIK this must be a duplicate Index.

How do I get around this error ?
