What Joshua is referring to is the ability to seed a backup copy job of a VAW to VBR job. This way they can have both local and cloud backups. Currently, when in the configuration of a backup copy job for Agent Backups, there is no ability to map backups. Only if you do it directly from the VAW, which wouldn't allow for cloud backups.
