Back Up Now button in the Topology page is unavailable after a failed backup

Description

After a backup fails, for example, because a volume in a resource group is offline, the Back Up Now button in the Topology page is unavailable even after the volume is brought back online, and the resources are refreshed.

Corrective action

Use the Refresh Resource button on the main Resources page, and then navigate back to the Topology page. The Back Up Now button displays correctly.
