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

According to the Veeam Backup & Replication Best Practice Guide1, some of the reasons why it is recommended to have a Veeam backup server at each of the three sites are:

* Each site has production data. This reason is based on the principle of locality, which states that backup data should be stored as close as possible to the source data, to reduce network traffic and latency, and to improve backup and restore speed and efficiency. Having a Veeam backup server at each site allows you to perform local backups of the production data at each site, without having to cross the WAN or VPN connections between sites.

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

To make backup files immutable in a Scale-out Backup Repository, you need to use XFS extents with the reflink attribute enabled. This attribute allows Veeam Backup & Replication to create immutable backup files using the fast clone technology. If some of the XFS extents do not have this attribute enabled, they will not support immutability and the backup files stored on them will not be protected from deletion or modification1

The method that can be used to validate that the design meets target SLAs and does not exceed repository growth projections is to ensure job throughput matches extensions and cross-compare with available network throughput, disk speed and initial sizing calculations. Job throughput is the measure of how much data is processed and transferred by a backup job per unit of time. Job throughput can be affected by various factors such as network bandwidth, disk performance, compression, deduplication, encryption, etc. By ensuring job throughput matches extensions, you can verify that your backup jobs are running as expected and meeting the SLAs. By cross-comparing job throughput with available network throughput, disk speed and initial sizing calculations, you can identify any bottlenecks or discrepancies that might affect your backup performance or storage consumption.

The additional Veeam capabilities that must be included in the conceptual design for gold level systems are SureBackup and Secure Restore. SureBackup is a feature that allows you to automatically verify the recoverability of your backups by running them in an isolated virtual lab. This can help you meet the requirement of testing the gold tier backups to verify recoverability. Secure Restore is a feature that allows you to scan your backups for malware before restoring them to the production environment. This can help you meet the requirement of scanning all backups for malware before restoring.

The information related to the virtual infrastructure that is missing and must be collected during the discovery are the total number of virtual machines and the size of the source data set. These are essential metrics for sizing the backup components, such as proxies, repositories, and transporters, as well as estimating the backup storage requirements and bandwidth consumption. The other options are either already provided in the scenario (recovery time objective, backup window) or not relevant for the Veeam solution (speed of Fibre Channel fabric).Reference:Veeam Certified Architect 2022 Exam Guide, page 10;Veeam Backup & Replication v11: Architecture and Design course, module 3.

The reason that justifies the decision to separate out proxies for gold tier and silver/bronze tier is that gold tier virtual machines run frequently and should not share resources with lower priority virtual machines. This is because gold tier virtual machines have a high RPO of one hour or less, which means that they need to run backup jobs more often than silver/bronze tier virtual machines. Therefore, they should have dedicated proxies that can process their data without competing with other backup jobs for proxy resources. This can improve backup performance, reliability, and scalability for gold tier virtual machines.

The component that will help the customer meet their stated objectives is to leverage Backup Enterprise Manager to allow end-users to restore files within their scope.Backup Enterprise Manager is a web-based interface that provides access to Veeam Backup & Replication functionality, such as backup, replication, and restore1. One of the customer's business requirements is to develop a self-service portal and integrate it with the new backup solution.Backup Enterprise Manager can fulfill this requirement by enabling self-service file-level restores for end-users, as well as integration with help desk systems2. The other options are not related to the customer's recovery requirements, as they are either not necessary (option A, as indexing and RBAC policies are optional features), not sufficient (option B, as deploying the console and setting RBAC policies do not enable self-service restores), or not native to Veeam software (option C, as the technical requirements state that Oracle backups must be managed by Veeam, not RMAN).Reference:Backup Enterprise Manager,Self-Service File Restore.
