The gold tier backup jobs have the most stringent recovery point objective (RPO) of one hour for image backup and 15 minutes for transaction log backup. This means that they need to run more frequently than the other backup jobs and create more restore points per day. Therefore, to properly plan the backup copy job settings, you will need more information on the gold tier backup jobs, such as the number of VMs, the size of backups, the change rate, the retention policy, and the bandwidth available for copying backups to the offsite location.

The gateway is a component that acts as a data mover between the backup proxy and the backup repository. If the gateway does not have enough CPU, RAM and task slots assigned, it may not be able to handle the incoming data from the backup proxy efficiently, and cause a bottleneck at the target. By increasing the resources and task slots for the gateway, you can improve its performance and throughput, and reduce the load on the target2

The repositories should be configured as Scale-out Backup Repositories consisting of hardened repositories to easily allow for additional capacity to be added and to meet the immutability requirement.Scale-out Backup Repository is a logical entity that groups several backup repositories into a single pool of storage, and allows to add or remove backup repositories as needed1.Hardened repository is a Linux-based backup repository with immutability enabled, which prevents backup files from being modified or deleted until the specified retention period expires2.The other options are either not immutable (option A and C, as NTFS and XFS do not support immutability) or not scalable (option B, as ReFS does not support adding or removing extents in a Scale-out Backup Repository3).Reference:Scale-out Backup Repository,Hardened Repository,ReFS Limitations.

If the repositories are able to accomplish much higher throughput, a new issue that might come up is that the bandwidth between sites might not be sufficient to support the backup copy jobs that need to run daily between Fresno and Carson City. This could cause the backup copy jobs to fail, take longer than expected, or consume too much network resources. Therefore, it is important to measure the available bandwidth between the sites and compare it with the backup copy data size and window. If the bandwidth is not sufficient, some possible solutions are to use compression, deduplication, or WAN acceleration to reduce the backup copy traffic.

Based on the requirements, one of the factors that should be considered in the physical design when implementing the virtual machine replication between sites is to ensure that the proper firewall ports are open between the proxies at each site. This is because Veeam Backup & Replication uses network ports to communicate with backup infrastructure components and transfer data during replication. You need to make sure that the required ports are not blocked by firewalls or other network devices. For a list of ports used by Veeam Backup & Replication, see this article2
