Sql-server – SQL Server 2008 Express backup and restore to test

sql server

We have a database system currently in SQL Server 2008 Express that we want to copy to a SQL Server 2012 server for testing. Having never moved a SQL Server database I have a few questions.

1. Can I take a full backup without taking the database offline?
2. Our database is 6Gb, however our .LDF file is over 200Gb. Can I take just a backup of the data and not bring over the transaction log?
3. Is the right click Backup in SSMS better/worse than doing BACKUP DATABASE in T-SQL?

Just making sure I have my ducks in a row since I don't have a current test DB with any real data to test the process. Thanks!
