The error is with restoring the backup. It indicates there is a record
which has a foreign key that is pointing to a non-existent entry. This
usually indicates that the original database has a corrupt index, and
therefor didn't detect this entry when deleting the target record.

The fact the backup doesn't restore doesn't mean that the original
database isn't workign. You either need to remove the duplicate entry
from the original database and backup and restore to fix it, or restore
with inactive indexes and rebuild them later.
