New To Veeam Looking For Suggestions

[ReamesSC]

We are moving away from Unitrends backup in order to deploy an air-gapped backup solution supported only by Veeam. We are a medium sized school district, and currently have 20 sites, all connected with 1-2gb WAN links, except for one which is 256mb. For the purpose of setup, I have two physical servers, both with 16 cores, 128gb memory and around 56TB usable storage. One server is located at Site A, our core datacenter where approximately 60+ VMs are hosted on a 6 node VMware cluster. Site B is one of the other 20 sites with the same physical server for backup copies.

My overall plan is to run backups locally for all 60+ VMs at Site A to the physical backup server at Site A. Immediately following the backups, I plan to run a backup copy job to the physical backup server at Site B. From what I've read, based on the WAN connection, I may not need to deploy WAN accelerators. My principal question revolves around the best method to backup the other 19 sites, following a similar plan, main backups to Site A physical backup server followed by a backup copy to Site B. Once completely deployed, I will implement the air-gapped solution.

What is the best method for me to present the local storage on the Site B server as a remote repository to the Site A primary Veeam server? Should I set up a proxy server for this?

Should I plan to use another proxy server to handle the other 19 sites and locate it at the main data center Site A? Each site hosts two VMs and they range between 150-500GB total file size for each site. Any suggestions would be most welcome. Thanks in advance.

One additional question. One of the reasons I really liked Unitrends is it had a console window that would show you the status of your backups in a very concise way. It would display your VMs as a total number and show whether they were backed up and also whether backup copies existed. I know the Veeam console will display backup successes and failures as a list. Does Veeam have a front end that will show your backups in a concise manner? Does VeeamOne do this?
