C # Get the difference between two files and use it for incremental backup

Question

I want to create my own incremental backup solution using C #. How can I get the difference between two files (version 1 and version 2 of ABC.TXT) and then update the version of ABC.TXT version 1 with the difference? Appreciate some of the tips! Thanks!

Here's something that I'm just Google might be useful as a starting point:

Answer 3

Do you really need an incremental backup? Is there a reason you can't just replace version 1 with version 2?

And as John pointed out, you might be better off using an already existing and tested backup solution.

Answer 4

I'm not sure how exactly you will replace the text “difference”, as this can become quite complicated. But for an initial check, you can compare file sizes.
