You can't read the file because it's still attached by the SQL Server engine. You have to unattach the database in SQL Server before you can touch it.

Really, making a backup is not an operation for your application code. This is normally done as a scheduled task in SQL Server. A DBA usually sets this up.
You do not have access to the folder with your current user - you either need to impersonate a user who does have access permissions, or change the permissions on the folder. The other thing to consider is that since this is in an SQL DATA folder, there is a good chance that the file is going to be in use by SQL when you try to copy it, and the copy will fail because the file is in use.

If this is an SQL database, why not back it up using SQL itself instead? This might help: Backing up an SQL Database in C#[^] (it's in C#, but teh code shoudl translate very easily.
