How can I registrer Data so I can reuse it instead of working on it right after ?

Hi ! 

This might sound a really basic question for you guys, I checked in the historic I did not find the answer somewhere else.

Right now I am acquiring data , and applying a post processing VI right away on it to try to improve the result ( Microscopy technology, trying to do the best pictures possible)

My technic today is to scan an object. By that I mean my acquisition has an end by itself, its not a non limit acquiring system.

I would like to be able to register easily somewhere the data of one shot, so I can try on it later on by charging it all the technics I would like to try.
The goal is to keep the same sample.

Right now I can do that, as long as I dont switch off computer. My aim is to have a file with the data that I can easily upload in the VI process.

I wonder if I am clear, my English is not top of the notch.

Could you help me doing that ? 
I can t send you the VI so yo ucan have an idea of what I am doing, I have a lot connected on each other, it would be too big.
I join to this post a picture of the VI at the moment where data arrives and go into the post processing VI

On the top right you can see something I just added, something which seems going into my diection.
Is it a good idea ? Is it the right place to put it ? 

Thanks a lot for your help !
