RSync without deletion
 

I'm using rsync for a backup-sript at the moment and want
to keep all files. The files are always unique, so I want
to rsync without delete any file on the destination.

I've tried with --no-delete and --max-delete=0
but nothing seens to work. Is there even a possibility to do so?

Thanks.

What happens if you don't use the --delete option ?

i don't use --delete so it should be an implied option
