PostgreSQL database in conjunction with the <a href="/doc/MusicBrainz_Server">MusicBrainz Server</a> software to automatically stay in sync with the main server. This is accomplished by downloading <a href="/doc/Replication">replication</a> packets (served from <a class="external text" href="https://metabrainz.org" rel="nofollow">metabrainz.org</a>) at hourly intervals and applying them to the local database. This enables a local mirror server to never be more than about an hour off sync with the main server. <p>Please note that we do not offer hosting services. If you wish to set up a MusicBrainz mirror you must do so on your own servers. <h2><span class="mw-headline" id="Licensing">Licensing</span></h2><p>The replication packets are licensed under the Creative Commons <a class="external text" href="http://creativecommons.org/licenses/by-nc-sa/3.0" rel="nofollow">Attribution-NonCommercial-ShareAlike 3.0</a> license. <p>Non-commercial / personal users may sign up and <a class="external text" href="https://metabrainz.org/signup/noncommercial" rel="nofollow">obtain a free access token for Live Data Feed</a>. <h2><span class="mw-headline" id="Commercial_use">Commercial use</span></h2><p>If you are interested in commercial use of our data, how we define commercial use or sign up for commercial use, please see the <a class="external text" href="https://metabrainz.org/supporters/account-type" rel="nofollow">MetaBrainz Foundation</a> site. <p><b>Please note that MetaBrainz does not charge for access to the data. However, we ask that commercial users support our efforts financially.</b> Anyone can <a href="/doc/MusicBrainz_Database/Download">download data snapshots</a> that are at most a few days old (which is better than our closest competitors) or use our <a class="mw-redirect" href="/doc/XML_Web_Service">web service</a> to have instant up to date access to the data.
