sql logs on windows2008R2&BE2010

[MyLee]

we have sql2005, be2010 and windows2008R2 environment.

when i take full backup on sql database, the log will not truncate or remove. i use simple recovery mode.

i saw on website and manual it will truncate the log. how can i remove logs?

After Full backup run "Log - Back up transaction log". This job wil truncate committed transactions.

If you are using simple recovery mode, you don't have to truncate the logs.  In this mode, the SQL Server will automatically truncate the logs when a commit is done.

You only need to truncate the logs when you are using Full Recovery Mode.

I need to research again how it on earth truncate the log or not.

the above answer make me confused.

thanks both.
