I think we need more information. Do you want to overwrite the data in the existing database with the data from last month, or do you want to integrate the data with what is in the existing database?

If you are looking to overwrite the existing database, doing a restore from backup will likely do the trick. RESTORE DATABASE x FROM DISK = 'somepathwithbackupfile'

If you are looking to mix all the data together, that could be a little more interesting, and leads to a whole new set of questions

Restore the backup into a newdatabase and merge the data into the main one?

INSERT INTO MainDatabase.dbo.MyTable
SELECT *
FROM RestoredDatabase.dbo.MyTable

obviously you will have to watch out for any data that already exists.

Alternatively you could make some views (in a third database) - this would probably be OK [performance-wise] if you just wanted to make a few reports, but keep the old and new data segregated in different databases

CREATE VIEW dbo.MyTable
AS
SELECT *
FROM MainDatabase.dbo.MyTable
UNION
SELECT *
FROM RestoredDatabase.dbo.MyTable
