SQL-Server-2008

I am working on project in which I have used visual c# as front end and sql express 2008 r2 for backhand.

Now I know that sql express database is having data size limit is of 10 GB, so I have written the code for database backup when pick limit is reached and I empty the database once the backup is successful.

I want to know what will be best approach to restore the backup file so that my current applications backhand (which i have empty earlier) should not be disturb.

Is it okay if i restore the same in my current database, in that case i have question to ask does it affect my applications working, as my application is kind of real time and after every 15 min. interval stored some values in database.

Whether I need to write some other utility for seeing the old data..?

thanks in advance..!!

the solution i got it from somebody.. posting here so that somebody if encountered with same situation can get the hint..

one database ("Current DB") that stores the real-time data.

when it comes to a size, it is dumped (or copied mdf+ldf) to archive.
and stored with time stamps (FROM-TO).

When data is needed, the relevant mdf is attached as a new "offline" database.
(you can use a connection string to attach MDF file to an SQL Server.)
and use that connection instead of the live one.

The application can run smoothly on the On-line database.
while reading, loading etc...
is done from the temporary attached and detached database files.
