Testing transaction log autogrowth behavior in SQL Server
An expert runs various tests to demonstrate how transaction log files respond to several T-SQL commands and to determine whether shrinking files is necessary. Big data projects go beyond IT infrastructure Big data creates a big test for enterprises: finding the right employees who can meld the technology and business needs in a way ..
Members of the Windows Administrator group have this right and can grant it to other users by adding them to the Perform Volume Maintenance Tasks security policy. In general you should grant the right to the group rather than the current account (any new account should be in the standard group and inherit its permissions)
SQL Server Forums - deleting transaction log file
To empty a data file by moving data from the data file to other files in the same filegroup, use the DBCC SHRINKFILE statement and specify the EMPTYFILE clause. You cannot remove a file from the database unless the file has no existing data or transaction log information; the file must be completely empty before it can be removed
How does shrinking a SQL Server log file affect performance? - Database Administrators Stack Exchange
One thing I find problematic is "I perform 2 Full backups daily so the log should not really be necessary as far as data roll-forward is concerned." The log is extremely important for points between your full backups. The quintessence is that there's only two really good ways to do transaction log handling: Either go with regular LOG file backups and the LOG-file will reuse it's space after each LOG backup and won't grow indefinitely, or Use SIMPLE recovery model and don't have to care about your LOG-file size, as you do regular full backups
sql server - How to identify which query is filling up the tempdb transaction log? - Database Administrators Stack Exchange
avoid enabling triggers for bulk operations avoid overuse of LOB types (max types, XML, etc) as local variables keep transactions short and sweet don't set tempdb to be everyone's default database - You may also consider that your tempdb log usage may be caused by internal processes that you have little or no control over - for example database mail, event notifications, query notifications and service broker all use tempdb in some way. breaking up a humongous query into parts may be slightly less efficient, but if it can avoid a huge memory spill to tempdb because the single, larger query requires a memory grant too large..

So considering that you set your database to Full Backup you need to either stop doing that and switch backup to Simple Recovery Mode or start doing backups correctly and your log will be trimmed by backups.

How to shrink a SQL Server Log file with Mirroring enabled? - Stack Overflow
Note that The 'Nul' is not a misspelling, it is an old DOS trick that behaves as if you are writing a file, but really just dumps the information off into the ether so it doesn't take up space on the machine. However, no log records are being sent to the mirror database, and if the principal should fail, the mirror will not have any of the transactions from the principal from the point the principal entered the exposed state

How to Truncate Log File in SQL Server 2005 - CodeProject
Log files are created in Full mode for a purpose and there's a point to Full recovery mode - this answer and the whole article is not the right place to discuss that, most basic SQL 2005 documentation covers that topic properly.
