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 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.

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

The additional condition of the offsite backup that is presumed by the immutability requirement is that a copy of backup data must reside in a public cloud local to each region.Immutability means that the backup data cannot be modified, deleted, or overwritten by anyone, including the backup administrator, the cloud provider, or malicious actors1.Veeam Backup & Replication v11 supports immutability for backups stored in Amazon S3 and Microsoft Azure Blob Storage, using the Object Lock feature2. Therefore, the offsite backup must use one of these cloud providers, and must be located in the same region as the source data, to comply with the data locality and privacy laws. The other options are not related to the immutability requirement, as they are either already stated in the business requirements (option A), technical requirements (option B), or not relevant for the Veeam solution (option C).Reference:Immutability,Object Storage Immutability.

If the recovery point objective (RPO) of gold tier machines changes from one hour to three hours with daily retention set to seven days, the impact on the Veeam design is that proxies will require fewer resources. This is because the backup frequency and the number of restore points for gold tier machines will decrease, which means that less data will need to be processed and transferred by the proxies. Therefore, the proxies will have lower CPU, memory, disk, and network utilization and can handle more backup tasks with the same resources.
