MongoDB Ops manager backup issue I want to deploy backup features using mongodb ops manager version 1,8. I have already installed ops manager and it's running but while i am clicking on backup tab it's showing below message. Please suggest how can i fix it.

"Backup is an optional module, which has not been configured for Ops Manager your installation"
In the version 1.8, the backup was optional as the documentation says. That version is quite old, the current version is 3.4 where backup is included to ops manager package.
