This process is called as Archiving.

Generally all companies do this process to improve performance of application, if you have Millions of records, then select statements would take plenty of time to display output, so archive unwanted data and put historical data into other (History) database.

If you are using any COTS product, an application which is not build in house, but you bought it from outside ( Vendor product). Then generally Vendors provide script to archive data.

If application is built in house, then you can do this,
SQL Server by default does not provide any feature that I know of.. which you can use to archive history data. You need to write script /DTS / SSIS Package that will load data from your main database to history database. And schedule this script /DTS / SSIS Package monthly / bi-monthly ( Of-course during maintenance window).

While loading data into History Database make sure you check the order to load ( Load data first in parent table and then child table, Foreign Key relation Ship). and while deleting data from your main database, delete first from child tables and then from parent tables.

This should take care of Archiving.

I would like to know more about backup and restore. I need to separate operational db and history db. The operation db will store only data for 6 months. The history db will store everything. How can I implement this ?

Thanks
