If you need to create an immediate backup for a hosted Redesign application, use the VRA Catalog Item "Instant Backup".
This runs the same job that creates the nightly backups.
A use case for this may be if you need to troubleshoot a problem, but the data was entered on the same day, and the backup from the previous night is too old.
Run Instant Backup, then deploy a "Redesign Test" to restore that backup into the Test. Redesign Test and Redesign Train will always find the most RECENT backup to restore.
