First, you'd need engineers to measure -- what's going on. Who is the slowest part? The network (most probable)? The post- gres replication process? The disk that postgres reads? The bar- man itself? Receiver disks/S3 daemon/etc? TLS of one of the above? Measures is the key. Then the solutions may be searched.
btw, a modern postgres can definitely supply 1GB/s to barman on a modern system. This is not a much, and probably could be im- proved by special tricks like rsync or manual prefetch or incre- mental copies -- however, it's less than 6 hours estimate and therefore is fine for you.
