Start backing up one or more applications

Arpio backs up (creates recovery points for) applications automatically based on their configured recovery point objectives (RPOs). A backup is also started automatically whenever an application's settings are changed (for example, when resource selection rules are modified). This API endpoint may be used to start backing up the specified applications at any time. Backup is an asynchronous process. This endpoint returns before the backup process starts, and the response representation may not indicate that the process has started yet. Poll application status to monitor backup progress. If a backup is currently in progress for a specified application, the running backup process is not interrupted or canceled. Instead, the manual request to perform a backup is ignored for those applications.
