WAN accelerators are dedicated components that Veeam Backup & Replication uses for WAN acceleration. WAN accelerators are responsible for global data caching and data deduplication, which reduce the amount of data that needs to be transferred over the network. By adding WAN accelerators to each site, you can improve the performance of backup copy jobs between sites, and reduce the bandwidth consumption and network traffic3

The best way to accomplish the recoverability testing of backup files for gold tier virtual machines to meet the customer's requirements is to create a virtual lab in the customer's environment, and then use SureBackup jobs to verify backups. A virtual lab is an isolated environment where you can run your backups or replicas without affecting the production environment. A SureBackup job is a process that allows you to automatically verify the recoverability of your backups by running them in a virtual lab. By using these features, you can ensure that your backups are consistent, functional, and compliant with SLAs and regulations.

According to the Veeam Backup & Replication Best Practice Guide1, the proxy and repository servers are the components that should be sized correctly to ensure that synthetic operations and backup copy jobs can be completed in the desired window. This is because:

* The proxy server is responsible for retrieving data from the source and sending it to the target. The proxy server performance depends on the CPU, memory, network, and storage resources available. The proxy server should have enough CPU cores and memory to handle concurrent tasks, as well as sufficient network bandwidth and storage throughput to transfer data efficiently.

* The repository server is responsible for storing backup files on the target storage. The repository server performance depends on the CPU, memory, network, and storage resources available. The repository server should have enough CPU cores and memory to handle concurrent tasks, as well as sufficient network bandwidth and storage throughput to write data efficiently. The repository server should also support the backup format and retention policy chosen for the backup copy job.

The retention requirement for this project is 12 weekly backups, six monthly backups and seven yearly backups.This is stated in the business requirements section of the scenario, where it says ''To meet regulatory requirements, backups must be retained for four years.'' This implies that the backup data must be archived for long-term retention, and the Veeam solution supports the 3-2-1 rule, which means having three copies of data, on two different types of media, with one copy off-site1. The other options are not retention requirements, but rather technical requirements or design choices, such as having on-premises backups on hardened repositories, having at least one copy of data on-premises, or having 14 daily backups on-site.Reference:Veeam Certified Architect 2022 Exam Guide, page 9;Veeam Backup & Replication v11: Architecture and Design course, module 4.

The direct risk of having Veeam Backup & Replication on the production domain is that a compromised Domain Admin could gain access to the backup server and its data. This could pose a serious security threat to the backup infrastructure and the customer data, as a malicious Domain Admin could delete, modify, or encrypt the backups, or restore them to a compromised environment. Therefore, it is recommended to isolate the backup server from the production domain and use a separate local administrator account for managing it.
