            <title>[SERVER-36200] Create a BackupCursorService class to manage backup cursor ownership</title>
                <link>https://jira.mongodb.org/browse/SERVER-36200</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Only one WT backup cursor can be open at a time. The fsync + lock command opens a backup cursor which is kept open until `fsyncUnlock` is called.&lt;/p&gt;

&lt;p&gt;The new filesystem backup story will continue to use backup cursors, but via a different command (that among other things, does not take out a global exclusive lock). There will also be new storage engine API methods for working with the new filesystem backup story. &lt;/p&gt;

&lt;p&gt;This ticket is to create a service class that sits above the storage engine that will dictate the semantic that only one cursor is allowed open at a time. Also part of this ticket is having `fsyncLock/Unlock` go through this service class.&lt;/p&gt;

&lt;p&gt;New methods for the upcoming backup work should not be speculatively done as part of this ticket.&lt;/p&gt;</description>
