SQL Serever DB Size Issue

Hi All,

  We have SQL Server 2008R2 in our setup. In it a Database  is of  size 150GB. We have dropped tables on the big database and cleared around 130GB (Logical).  So our point is how can we reduce the DB Physical size apart from shrinking it.

    Can we take a backup and restoring it would reduce the size? Please suggest the options we have to physically reduce the DB File size.

Regards,

Varun
