Microsoft SQL Database - Backup and Restore

Hello! I need to learn how to back up and restore a **Microsoft** SQL database. I believe that there are several different methods to achieve these results, so I'll better explain the case. I have a few servers running independent SQL databases. These servers aren't connected to each other by any means. They are completely independent. I need a way to fully back up the SQL database into a folder, on a daily basis. This folder will then be included on my daily tape backup. I will NOT give access to any of my servers and the coder's job will be to provide me with remote access to his/her computer and teach me the back up and restore process. Alternatively, I can set up a test computer so that the programmer can show it to me there. If this is the case, it'll be part of the coder's job to install SQL server and create a dummy database for us to test the back up and restore process.
