&lt;p&gt;Yes, it appears that other files (in addition to one originally provided) are corrupted likely as the result of disk failure. Unfortunately, in cases like this, we cannot attempt repair the the damaged files.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;

&#160; &#160; &#160; &#160; My MongoDB is in single node mode. This is the file I backed up earlier. It was wrong when I restored the server. I have only one wrong backup file now. Is it totally impossible to solve it?&lt;/p&gt;

&lt;p&gt;Thank you,&lt;br/&gt;

&lt;p&gt;Unfortunately, this error indicates that there was corruption on the disk, most often caused by a faulty storage layer beneath mongod. In this situation, our best recommendation would be to &lt;a href=&quot;https://docs.mongodb.com/manual/tutorial/resync-replica-set-member/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;resync the affected node&lt;/a&gt; or &lt;a href=&quot;https://docs.mongodb.com/manual/core/backups/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;restore from a backup&lt;/a&gt; if possible.&lt;/p&gt;

&lt;p&gt;To prevent this type of problem in the future please take note of the following guidelines to help mitigate any issues related to unreliable storage layers or server failures. &lt;/p&gt;

&lt;ul class=&quot;alternate&quot; type=&quot;square&quot;&gt;
	&lt;li&gt;Make sure your &lt;a href=&quot;https://docs.mongodb.com/manual/administration/production-notes/#disk-and-storage-systems&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;underlying storage is configured in an optimal way&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;Schedule and perform regular checks of the integrity of your filesystems and disks.&lt;/li&gt;
	&lt;li&gt;Make sure to update MongoDB to the &lt;a href=&quot;https://docs.mongodb.com/manual/release-notes/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;most recent version&lt;/a&gt;.&lt;/li&gt;
	&lt;li&gt;Never manipulate the underlying database files in any way while &lt;tt&gt;mongod&lt;/tt&gt; is running.&lt;/li&gt;
	&lt;li&gt;Always keep up to date &lt;a href=&quot;https://docs.mongodb.com/manual/core/backups/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;backups of your databases&lt;/a&gt; and verify that you have a process in place to restore them.&lt;/li&gt;
	&lt;li&gt;Use a &lt;a href=&quot;https://docs.mongodb.com/manual/replication/&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;replica set&lt;/a&gt; for improved reliability.&lt;/li&gt;
&lt;/ul&gt;


&lt;p&gt;Thank you,&lt;br/&gt;

Please extract these files and replace them in your &lt;tt&gt;$dbpath&lt;/tt&gt; and let us know if it resolves the issue.
