Transactional Replication re-initialize from backup

Good evening Colleagues,

So question goes like this. If I use the option to create a publication that allows initialization from backup and then a pull subscription all is well so far.

What happens when for whatever reason the subscription is asking for re-initialization, what are the steps involved,

for ex:
Drop the subscription -> take published db backup -> restore it on top of subscribed db -> recreate subscription.

 Many thanks,

Archie
