difference in behaviour of --filter --delete: cmdline vs. file

[Kevin Korb]

It is a little confusing but in order to have an exclude dir merge
filter do both things (prevent transfer and prevent deletion) then it
needs to be on both ends of the transfer.  The file on each end only has
partial effect on what rsync does.

Think of it like a file you (as a regular user) can make in your home
dir telling the backup system to not backup a file.  If that file has
already been backed up rsync will also remove it from the backup on the
next run.
