We have a customer how has a 10Gb Sat link between the HQ and the DR site. On a 10GB Satellite WAN link, the 4 to 5GB of backup takes more than an hour which is highly unacceptable. The WAN is connected via Cisco Router and the routers are not doing any kind of traffic filtering or policing.
The customer also has jumbo frame enabled (on the network equipment?) at the HQ, but at the Dr site, the jumbo frame is not enabled
Could this possibly allow the Customer to have good experiences locally in HQ with the jumbo frame enabled, but then compromised when data is transferred externally to the non-Jumbo Frame site?
I don't know if using a satellite link eventhough with the 10Gb bandwidth causing this issue.
