I am new with duplicati, I would like to know if it is possible to make the backup just like the original file, example:
musica.mp3 and in the backup it will be musica.mp3 instead of being a zip file in several pieces
Welcome to the forum!
Duplicati is not a file synchronization tool. Its core design is around deduplication, so it will break files into chunks and store unique chunks in ZIP volumes on the back end. There is no way to disable this behavior.
What you lose out on is files backed up in native format, but what you gain is efficient storage of many backup snapshots on the back end.
Hope this helps.
