size Source vs Backup

Hello, is the difference that appears between the origin and the backups normal?


it may be caused by data that compresses very well, and few changes between backups. If you have one file of 500 GB filled with zeroes, it will compress to a few KB. I don’t know of a command that describes how disk space is used on the backend, maybe because this could be tricky given that Duplicati manages deduplication.
