How Recovery Appliance Processes Backups in Backup Polling Directories
To set up polling so that backups are copied to Recovery Appliance storage, you must configure a backup polling directory that exists outside Recovery Appliance storage locations, but which the Recovery Appliance can access. The protected database writes its backups to the polling directory, which you specify in the polling policy.
The Recovery Appliance checks the polling directory for newly created backups. When backups exist, the Recovery Appliance copies the backups from the polling directory to its internal Recovery Appliance storage location, and then processes them. After enough time has passed for Recovery Appliance to copy the backups, the protected database deletes the backups from the polling directory. Figure 2-8 depicts this configuration.
