Don't you have SQL Server Management Studio?

If you "attach" in SSMS, then you will be able to backup and restore using the "Tasks" menu.

"Restore" is usually something done "intentionally"; and not under program control (as are backups).

That's not a DB that needs a restore - you are attaching it, which is a special "developer mode" of SQL Express (that isn't available in the full version) which temporarily hands the file to SQL server, and spins up a separate instance of SQL to handle it. When the connection is closed, the file is released by SQL.

So backup and restore of that file is a file system function, nothing to do with SQL. Look at how you backed the file up, and it should be fairly obvious how you restore it.
