Development has created 7 day rolling tables on multiple servers. I want to pull this data over to another table so I can trend daily averages over a few months. The rolling table is populated throughout the day meaning data is added/removed every few minutes. What would be the best method to copy this data to my table without missing or creating duplicate rows?

Step 1 would be to find out how they are deleting the data so you can intercept it.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

Replication could be problematic as SQL will replicate the DELETEs as well as the INSERTs.

Also, do you need to capture UPDATE activity or just INSERTs?

Finally, are you on Enterprise or Standard Edition?

CDC could work well for this if you are on Ent Ed (unfortunately, CDC is not available on Std Ed).

SSIS lookup is working well.
