Backup Process
Backups depend upon which version of MongoDB your database is
compatible. This
Feature Compatibility Version ranges from the current version to one
version earlier. For MongoDB 4.2, the FCV can be 4.0 or 4.2.
Backup Definition and Operational States
Each backup is defined as a job. Each job defines how much and how often data is backed up. Backup jobs are defined on a per-project basis.
Operational States
The following table lists the states of a backup job:
Change Operational States
Once backup jobs are active for a project, they run without further intervention until they are stopped or terminated. The operator can change the state of a backup in the following ways:
Backup Process Flows
Once created, a backup job goes through the following process flow:
Regional Backup
You can assign backup jobs to Deployment Regions to promote data isolation. When you assign a backup job to a deployment region, Ops Manager writes all snapshots, oplogs, and sync data that the job generates to the relevant storage configured for that region. Regional backup is available for replica sets and sharded clusters. To enable regional backup for a sharded cluster, you must assign deployment regions and initiate backup jobs for each shard separately.
