I have two hard drives ("b4old" and "b4"). They both contain some duplicate files (although metadata such as modified/created dates may differ), but there are some files on b4old that are not present on b4 at all. I want to rsync only those files onto b4.

I tried to run the below command as a dry run, but I checked the log and there are files completely missing on b4 that aren't in the log. What am I doing wrong?

sudo rsync -avvxHAWX -n --numeric-ids --info=progress2 /srv/b4old/ /srv/b4/ --log-file=/config/2023-05-27-1243-rsync.log

rsync --ignore-existing -av source/ destination/ -- This is important if you justy want to copy the missing stuff. --ignore-existing will not copy/modify existing files on destination from source.

Thank you, I actually did include --ignore-existing. After I ran the dry run, I looked for one specific file that I know to be on the old drive, but not the new, and it wasn't listed at all. I'm not sure where else to look, unless one of my other options somehow caused that file to be filtered out.
