I need to create an incremental backup (only files with more recent date changes). I used to be a fan of Cobian soft, but it seems to want to copy every file nowadays. I only need to copy about 300MB of changed data. I don't want to tax my back up HD and write all 800 GB over again.
I used the Windows "copy and paste" command to backup a hard drive with movies and pictures about 6 months ago. Now I want to add onto my backup without rewriting those original files. I actually found a nice utility called bvckup that smartly only updates things that changed, but it MIRRORS the task. It deletes things from the destination directory that aren't in the source directory!
