My question Backup with local manifest was marked as a dupe of Improve RSYNC scan speed / Alternate approach?. But it's not

The other question asks how a rsync scan can be sped up in general. The answer to the other question refers to a new rsync version where the file transfer can already start while the files are still be compared. I already use that version.

My question asks whether, after an rsync, I can somehow store a manifest/directory/whatever of my local==serverside files, to make the file list construction for the next backup a process that can happen entirely locally (without a network connection). I know that the backed up files won't change on the remote server, so this should be possible.

How can I object to the 'dupe' tag?
