Then it isn't really a backup. A lower-bandwidth failover capacity is properly described as an alternative or degraded pathway. To be a proper "backup" a thing has to actually do the primary job at least temporarily.
aye. Starlink could be, best case, an Out of Band (OOB) management interface.
good for getting into the other side of a connection or doing some management tasks like back-up telemetry -- but we're talking SNMP, SSH connections to routers, etc, not GigE levels of data.
