                <link>https://jira.mongodb.org/browse/DOCS-1296</link>
                <project id="10380" key="DOCS">Documentation</project>
                    <description>&lt;p&gt;Hi,&lt;/p&gt;

&lt;p&gt;some comments on &apos;http://docs.mongodb.org/manual/tutorial/backup-databases-with-filesystem-snapshots/&apos;:&lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;section &apos;Backup and Restore Using LVM on a Linux System&apos;, subsection &apos;Archive a Snapshot&apos;, I am reading &apos;dd if=/dev/vg0/mdb-snap01 | gzip &amp;gt; mdb-snap01.tar.gz&apos;: why .tar ?  This is not a tar file, should we not read &apos;dd if=/dev/vg0/mdb-snap01 | gzip &amp;gt; mdb-snap01.gz&apos; instead ?&lt;/li&gt;
&lt;/ul&gt;


&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;section &apos;Backup and Restore Using LVM on a Linux System&apos;, subsection &apos;Restore a Snapshot&apos;: same as above for &apos;gzip -d -c mdb-snap01.tar.gz | dd of=/dev/vg0/mdb-new&apos;, and if not fixed for some reason, you might want to update &apos;Uncompresses and unarchives the mdb-snap01.gz into the mdb-new disk image.&apos; which correctly refer to a file without &apos;.tar&apos;.&lt;/li&gt;
&lt;/ul&gt;


&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;section &apos;Backup and Restore Using LVM on a Linux System&apos;, subsection &apos;Remote Backup Storage&apos;: same as above.&lt;/li&gt;
&lt;/ul&gt;


&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;section &apos;Backup and Restore Using LVM on a Linux System&apos;, subsection &apos;Remote Backup Storage&apos;: the procedures described in this section use lot of bandwidth, is it done on purpose (remove CPU usage on the server serving the database) ?  A note might be welcome to explain the trade-off between doing local and remote compression/decompression.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Feel free to contact me fore more information.&lt;/p&gt;

&lt;p&gt;Best regards,&lt;/p&gt;

                            <comment id="298051" author="samk" created="Mon, 25 Mar 2013 18:07:41 +0000"  >&lt;p&gt;Fixed the file extension. &lt;/p&gt;

&lt;p&gt;It doesn&apos;t make sense to compress locally and then offload to (ssh automatically compresses it&apos;s operations,) so compression locally would be redundant, and take even more resources from a presumably production system. I think the decision to create the gzip file depends on available space which is mentioned and other considerations that are beyond the scope of this file.&lt;/p&gt;

&lt;p&gt;I&apos;m going to close this ticket for now, but feel free to comment or reopen if you think we need to do more work. &lt;/p&gt;

&lt;p&gt;Cheers,&lt;br/&gt;
