All of our related products have disappeared. If I look in the database the 'catalog_product_link' table is empty.
I have a db backup which has the data in it. Can I just import the data from the back up into the 'catalog_product_link' and 'catalog_product_link_attribute_int' tables or is there more to it?
Note that I can't just restore the full database from the backup - it's too old and too much has potentially changed
The products are a mixture of both configurable and simple with visibility set to catalog/search
