I'm curious if TI (I'm on TI 10), when creating an incremental or differential, looks at the archive bits in the data, or if it looks at the full image of its own backup set? The reason for this question is I'm wonder if I had two backup sets running during the same time frame, if they would be truly independent of each other, or if they would confuse each other. I'm not actually going to do this exact scenario, but lets say I set up backup location A and backup location B, on the same external hard drive. I set up two tasks, one for each backup location. Each task is run daily (at different times of the day, not concurrently), and each one is set (in backup locations) to create a new full after X number of incrementals. Would the incrementals look to the full backup file in their own backup location, each independently, or would the incrementals going on in the other backup location cause the wrong files to written, or file to not be written, in them? Will both backup sets keep full integrity?
