Restoring a backup that was created from the Database Administrator Backup and Restore utility is performed using the same utility. This will restore the backup into the current, active database. If you do not want to do that, you must first create a new database. During the database creation, you can elect to use your backup as the source for the new database.
Restoring a backup using an FHX file as your source is more involved. All steps are covered in more detail in the Database Administrator online help (each utility has a help button on each dialog) and the DeltaV Explorer online help.
Select No to All when prompted to overwrite existing items during the import.
The download should be performed only when no import errors are present in the log file or have been addressed. Import errors can mean that some items in the database were not successfully imported making the current database incomplete and not suitable for download.
