Sync files-from with delete

[john espiro]

I have a local directory that I am trying to sync with a remote directory.  That's fine, but there's a lot of data that is out of sync so I decided to make a local copy of the difference to then bring to the remote location.


So I ran a dry-run between the two to generate a list of files in listOfFiles.txt

Then I ran rsync from local to localBackup.


rsync -av --files-from=/tmp/listOfFiles.txt /var/MyData/ /USB/Backup/


Now, while this is happening, I am still rsycning between my local and my remote.  So I re-generate the listOfFiles.txt, which contains less things to copy than before.... I'd like to delete anything in /USB/Backup that is not in the listOfFiles.txt

TLDR: I want to make a local backup of the differences between local and remote and sync them to a separate local drive.

Thanks...
