In the event of a disaster, when the production CommServe host becomes unusable or inaccessible, or if the CommServe host is moved to a new hardware, the latest Disaster Recovery (DR) backups can be used to rebuild the CommServe host.
When a Web Server (where MongoDB database is hosted) becomes unusable or inaccessible, or if the Web Server is moved to a new hardware, the latest DR backups of the MongoDB persistant data can be used to rebuild the MongoDB database.
Important
Once restored, the database reflects the state of the production CommCell group when the DR backup was performed. Based on the frequency of the DR backup, you may lose some data such as information about backup operations, entity creation or configuration changes, when you move the CommCell operations to the standby CommServe host.
