Delete file on destination only if source was delete at least X days before.

Rsync has absolutely no knowledge of when a file was deleted.

Perhaps you are looking for something like --backup and --backup-dir
to temporarily preserve files instead of deleting them (then deleting
them with a simple rm -rf later)?

Or maybe you should consider an rsync --link-dest based backup system
instead of a simple mirroring that will allow you to keep many
complete old backups with minimal increase in disk space usage.
