What does BACKUP TRANSACTION WITH TRUNCATE_ONLY do?

$

Hi all,

I have a developer working before me who used

BACKUP TRANSACTION DB_Name WITH TRUNCATE_ONLY

in one of our ETL processes in SQL Server 2000. I've never come across this before and was wondering what it does actually? I see most of the people on this forum and web recommending not to use this. What kind of issue will I face if used the above?

As an alternative what kind of command I can use? Or doesn't it matter if I use it or not?

Background:

The ETL process runs once in a month which loads approximately 10,000,000 records into our database.

We do have a backup process going for this DB once in a week with a backup size of around 120GB.

Please throw some light.

Thanks
