How portable is SQL Server? Want DB on laptop, but want to easily back up or move.

I have this MS Access database on my laptop, and am developing a VB.NET app as a front end. I'm quite happy about the DB being on my C: drive -- it's a single-user system (the user being me), plus I don't have to worry about security or costs or connection difficulties if it's hosted on the Internet.

The nice thing about Access is its database can be a single file, hence easy to back up or move as and when necessary. But I dislike Access, plus I would rather like to use the stored procedures that SQL Server offers.

What's involved in backing up a SQL Server DB to a thumb drive, and then restoring to another machine if my laptop should die?

If you have SQL Server Management Studio installed, backing up and restoring is a few clicks. If you don't, it's running a commandline in a console window.

Thanks, will investigate.
