HOW Data source modification impact backup

hello guys!

I’m new to duplicati, I wanted to know a couple of things, let say I made a huge first backup and then I decide to re organize in complete new way my source data folder (renaming/moving files & folders), what happen on the backup side once I hit the run button, does duplicati transfer effectively all moved/renamed items or as I hope it does thanks to his block level algorithm it only transfer the change by re indexing the block in some ways. I hope I’ve been clear enough to be understandable I m not familiar neither in English nor in software backup.


If you move files around, Duplicati will want to reprocess them. This will cause the next backup to take a bit more time. But it will NOT need to re-upload any file data since the actual file contents didn’t change.
