rsync with --delete option

<p>Anyone know why:</p> <pre><code>rsync -azuv --exclude "*.db" --delete /etc/postfix/ /home/backups/system/etc/postfix/ </code></pre> <p>Would delete files from the destination that don't exist on the source (as it is supposed to), but:</p> <pre><code>rsync -azuv --exclude "*.db" --delete /etc/postfix/* /home/backups/system/etc/postfix/ </code></pre> <p>Doesn't?</p> <p>There is nothing "funky" about the files (as far as I can tell) that don't get delete by the second command - in other words, they don't start with a "." or anything. For the record (not that it matters) the files that weren't removed from the destination after I deleted them from the source were:</p> <p>postgrey_whitelist_recipients.rpmnew postgrey_whitelist_clients.rpmnew postgrey_whitelist_clients.local.rpmnew</p> <p>TIA!</p>
