Hi Reno,
I think the questions are probably answered in the other post, but just for the benefit of someone else who might read this,
Incremental images ( I think that's what you mean by recovery points) contain only the changed data rather than all the data. If your entire disk fails, you have to restore the most recent baseline first, then restore all the subsequent incrementels.
Say, you create a baseline image on Monday, and then incrementals on Tuesday and Wednesday. For some reason, Thursday your hard disk fails.
Now you restore the baseline created on Monday, but it does not contains your work on Tuesday and Wednsday. Then you restore the incremental image taken on Tuesday, which gives your work on Tuesday back. Once you restore the next incremental (taken on Wednesday), all your Wednesday work too will be there. Remember, the full backup on Monday will be much larger and takes longer time to create than incrementals on Tuesday and Wednesday, since they only contain data changed in a day.
Hope this helps,
Krish
