I read in duplicity's man page that "In order to determine which files have been deleted, and to calculate diffs for changed files, duplicity needs to process information about previous sessions. It stores this information in the form of tarfiles where each entry’s data contains the signature (as produced by rdiff) of the file instead of the file’s contents."
Where are these tarfiles stored? The cloud?
BTW rclone checks size/timestamp and/or checksum to determine what to upload, the same way rsync does. So you don't have incremental "snapshots" the way duplicity does.
