Restoring a replicated SQL Server database in a non-replicated testing enviroment
You have to just restore the database using 

restore database &lt;db_name&gt;
from disk = 'Disk path\db_name.bak'
with recovery, replace -- only if there is already database that you need to overwrite
,stats =10,
move 'logical_data' to 'physical_path.mdf',
move 'logical_log' to 'physical_path.ldf'


once the database is restored, you can remove the replication bit 

sp_removedbreplication 'database_name'
