I'm wanting to backup files based on changes in a similar way to how VSS (VolumeShadowService) does. That is, I want to backup the original file, then when it changes, just backup the blocks that changed, not the entire file again. That is, if I have a 200 meg file and only a couple dozen blocks change, I don't want to re-replicated the entire file like happens with the build in file provider.
How can I do this with Sync Framework?
