The new regulatory requirements mandate that the most recent 31 days of backups are immutable. To meet this, immutability must be configured for both the on-premises and off-site backup copies.

1. On-premises copy: A standard NAS repository using SMB or NFS protocols does not support Veeam's immutability feature. The correct procedure is to migrate the on-premises backups to a repository type that does, such as a Linux Hardened Repository. This repository type leverages single-use credentials and the immutability file attribute to protect data.

2. Off-site copy: The Amazon S3 repository can be made immutable by enabling S3 Object Lock on the bucket and configuring the immutability setting within the Veeam repository properties.

Therefore, moving the on-premises backups to a Linux Hardened Repository (D) and enabling immutability on the Amazon S3 repository (E) are the two necessary actions.

A. A standard NAS repository (typically SMB/NFS) does not support the immutability feature in Veeam Backup & Replication. This action is not technically feasible.

B. The requirement for 24 monthly restore points is already met by the existing backup copy job. Adding this to the primary backup job is redundant.

C. Configuring a Scale-Out Backup Repository is a prerequisite for using S3 with immutability, but it is not the action that enables it. The specific action is enabling immutability itself.

"Hardened Repository" section: This section details the requirements and functionality of the Linux Hardened Repository

stating

"To protect your backups from loss as a result of ransomware or other malicious attacks

you can prohibit deletion of data from the hardened repository by making it temporarily immutable." This supports option D as the correct method for on-premises immutability.

2. Veeam Backup & Replication v12 User Guide for VMware vSphere

"Immutability" (under Amazon S3 Object Storage): This section explains

"For Amazon S3 object storage repositories

Veeam Backup & Replication supports immutability... This feature helps to protect your data from being modified or deleted by malware or other attacks." This directly supports option E.

Module 4: Backup Repositories: This guide explicitly lists the repository types that support immutability: Linux Hardened Repositories

specific deduplication appliances

and object storage with Object Lock/versioning. It clarifies that standard Windows or NAS (SMB/NFS) repositories do not have this capability

making option A incorrect.
