You are able to take a look at numerous deployment techniques. You should use click once however i strongly advise using something similar to NSIS(free). Use a software HM NIS Edit(also free) that does the effort for any .internet project. Try the fit your personal machine and you will understand how to deploy. By client i'm guessing you mean your customer instead of client/server type client?

the response to three in my opinion (although i rarely perform the old file discussing nowadays) that you ought to put the file within the temp folder in home windows, however, i'm prepared to be wrong about this.

It is dependent on which data provider you're using however, you just produce a sqlcommand object(as i am sure you are aware how) then type in the backup sql something similar to:

          BACKUP DATABASE AdventureWorks2008R2 
              TO DISK = 'Z:\SQLServerBackups\AdvWorksData.bak'
              WITH FORMAT;
           GO

hopefully has assisted.
