            <title>[SERVER-26091] gridfs deduplication</title>
                <link>https://jira.mongodb.org/browse/SERVER-26091</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;With the original storage engine it was easy to organize incremental or differential backups, as the old files weren&apos;t tend to change. We also could choose which collection to backup, as one file meant one collection.&lt;br/&gt;
With the wire tiger we need much more backup space, even if one byte is save somewhere, many files are affected and so hashes are changed...&lt;/p&gt;

&lt;p&gt;Today we have discovered, that we have 560 copies of the same heavy file, and probably having deduplication functionality on gridfs is possible, or even easier then thinking of filesystem deduplication, that could also reduce the RAM amount mongo uses to cache the data from storage, so we want to ask to add that functionality. Thanks a lot,&lt;br/&gt;
at TUMO Center for Creative technologies we love you very much.&lt;/p&gt;</description>

&lt;p&gt;There are various options outside of MongoDB to achieve deduplication or efficiently backup MongoDB databases, including with &lt;a href=&quot;https://www.mongodb.com/cloud/cloud-manager&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB Cloud Manager&lt;/a&gt;.&lt;/p&gt;</comment>
                            <comment id="1383595" author="thomas.schubert" created="Tue, 13 Sep 2016 18:27:21 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=edikmkoyan&quot; class=&quot;user-hover&quot; rel=&quot;edikmkoyan&quot;&gt;edikmkoyan&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;Thank you for the feature request. I&apos;m marking this ticket to be considered by our Integration Team.&lt;/p&gt;

&lt;p&gt;I see that a &lt;a href=&quot;https://groups.google.com/forum/#!topic/mongodb-user/GbCJPGy04vc&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;similar request&lt;/a&gt; was posted many years ago on our user group. I would recommend considering whether Mathias&apos;s suggestion works for your use case.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;
Thomas&lt;/p&gt;</comment>
