On-demand snapshots will always be full snapshots, not incremental. This may cause considerable traffic from the current target node(s).
Warning
The extra snapshot may cause additional storage requirements, especially if the target node has changed.
Take On-Demand Snapshots
Note
If a snapshot is in progress, you can't initiate an on-demand snapshot on the Ops Manager UI or the Ops Manager Public API.
To take on-demand snapshots:
Click Continuous Backup, then the Overview tab.
On the line listing the process, click the ellipsis icon and click Take Snapshot Now.
On the pop-up modal that appears, configure the retention value and click Take Snapshot.
