Veeam Agents are designed to provide backup solutions for physical and cloud environments. They support various operating systems, including Ubuntu (a Linux-based OS) and Windows Server. These agents ensure that data on servers running these operating systems can be effectively backed up and restored. However, Veeam Agents do not support FreeBSD, IBM iSeries, or iOS as these platforms require different backup solutions or are not typically used in environments where Veeam operates.Reference:Veeam Agents User GuideVeeam Help Center: Supported Environments

To meet the new regulatory requirements, enabling immutability on both the NAS and Amazon S3 is essential. Immutability prevents backup files from being deleted or modified, aligning with the requirement to protect the most recent 31 days of backup files. By enabling this feature on the NAS and Amazon S3, the business ensures that both local and offsite copies of their data are secure and compliant with the regulation. The other options do not directly address the new requirements of preventing deletion or modification of backup files.Reference:Veeam Documentation: Immutability SettingsVeeam Help Center: Configuring Amazon S3 Immutability

Given the company has an RPO set at 4 hours, the restore point that gives the best RPO is the one closest to the time of the disaster without going over the disaster's timestamp. Since the disaster occurred on June 12, 2023, at 10:00 AM, the restore point at June 12, 2023, 9:30 AM would be the most recent one within the RPO threshold. This restore point minimizes data loss and provides the most current data before the disaster.Reference:Veeam Backup & Replication User Guide: Understanding RPO and RTOVeeam Best Practices: RPO and RTO Planning

The immutability period set on a Linux Hardened Repository prevents deletion of backup files for the duration of the immutability period. In this case, it is set to 60 days. However, the GFS (Grandfather-Father-Son) retention policy specifies that a monthly full backup is to be kept for 6 months. Since the full backup was created on 27th May 2023 and flagged as a monthly GFS backup, it will be retained for 6 months irrespective of the retention policy or the immutability setting. Hence, the restore point will be automatically deleted after 6 months, which would be on the 28th of November 2023.Reference:Veeam Backup & Replication User Guide: GFS Retention PolicyVeeam Help Center: Linux Hardened Repository Immutability

To enable backup from storage snapshots with a Nimble Array, it is necessary to add the storage system to the Veeam Backup & Replication console's Storage Infrastructure. This allows Veeam to interact with the Nimble Array and orchestrate the creation of storage snapshots, which can then be used for backups. Simply enabling the backup from storage snapshots option in the job is not enough; the array itself must be integrated into the Veeam infrastructure.Reference:Veeam Backup & Replication User Guide: Integration with Storage SystemsVeeam Best Practices: Nimble Storage Snapshot Integration

Given the proxy load of 68% and all other loads (source, network, target) at 0%, the bottleneck is at the proxy. To decrease the backup processing time and accommodate the growth of the environment, adding additional Windows or Linux machines as backup proxies would help distribute the load. This would enable parallel processing and reduce the time taken to complete the backup jobs, thereby helping to meet the RPOs.Veeam Backup & Replication User Guide: Backup ProxyVeeam Help Center: Managing Backup Proxies

To meet the 1-hour RPO for the databases within the VM, while only being able to snapshot the VM once per day, the best strategy is to enable regular transaction log backups (option A) and process transaction logs with the job (option E). This setup allows the system to capture changes in the SQL Server transaction logs at intervals less than the RPO requirement, without needing to snapshot the entire VM more frequently.Reference: Veeam Backup & Replication Documentation, Veeam Backup & Replication Best Practices Guide

Instant file share recovery is the most effective method to minimize service impact in this scenario. This feature allows users to instantly access the NAS data directly from the backup files without having to wait for the entire file share to be restored. This approach is beneficial when quick access to data is crucial.Reference: Veeam Backup & Replication Documentation, Veeam NAS Backup Guide

Instant VM Recovery to VMware offers the lowest possible RTO for restoring a physically damaged Linux server to a VMware vSphere infrastructure. This feature rapidly restores service by running the server directly from the backup file in a VMware environment.Reference: Veeam Backup & Replication User Guide, Veeam Agent for Linux Guide

Virtual Labs is the ideal feature for testing the impact of operating system updates in an isolated environment. Virtual Labs allow you to create a secure, isolated copy of your production environment where you can test updates, patches, and other changes without affecting the live environment.Reference: Veeam Backup & Replication Documentation, Veeam Virtual Lab Guide
