because I do not have a Subscriber backup, when restoring my Publisher database I first delete replication settings
exec sp_removedbreplication
-- Dropping the registered subscriber
exec sp_dropsubscriber @subscriber = N'SRV'
-- Dropping the distribution publishers
exec sp_dropdistpublisher @publisher = N'SRV'
-- Dropping the distribution databases
use master
exec sp_dropdistributiondb @database = N'distribution'
GO
/****** Uninstalling the server as a Distributor. ******/
exec sp_dropdistributor @no_checks = 1, @ignore_distributor = 1
restore Publisher db and re-create replication (using script previously generated with Management Studio )
this is the ony solution I've got
