Duplicate backup

Hi,

I get some confuses  about duplicate backup. I have full backup on weekend and incremental on week days. All backup to DISK. Now, if I Add Stage and choose duplicate to Tape. Then click Edit and click on Duplicate data immediately after source task complete. On the Source box, I choose Full.

So, the option "Full" here mean it will duplicate only full backup, right? If yes, what about my incremental back? will it be duplicated? Or I have to add another stage for my incremental backup and at the Source I will choose Incremental, right?

I get confuse about it. Please help.

Tho.
