Yes, it's possible. It's one of a workaround I thought. Then the backup data are as follows: a. The full backup taken at least 14 days ago. b. The latest 14 days backup data In this case, I concern the effect if (a) becomes too old. However, it might be a groundless fear. I'll give it some more thought. Thank you again.
