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.

The recommended step that Veeam Life and Indemnity can take to improve the latency encountered during backup of the virtualized MSSQL Server database running on vSAN is to implement Veeam Agent for Microsoft Windows on the virtualized MSSQL Server database servers. Veeam Agent for Microsoft Windows is a data protection solution that allows you to back up physical or virtual Windows machines at the guest OS level. Veeam Agent for Microsoft Windows can provide application-aware processing and transaction log backup for MSSQL servers, as well as support for vSAN storage snapshots. Veeam Agent for Microsoft Windows can also reduce the latency by performing backups without using VMware snapshots, which can cause stun issues on vSAN.

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 transport modes that could be used during the redesign for gold tier virtual machines with a one-hour RPO are Virtual Appliance (HotAdd) and Backup from Storage Snapshots. A transport mode is a method of retrieving VM data from the source storage during backup or replication. Virtual Appliance (HotAdd) is a transport mode that allows a proxy server running on a VM to attach disks of another VM to itself via hot-add SCSI commands and read data directly from these disks. Backup from Storage Snapshots is a transport mode that allows a proxy server to retrieve data from storage snapshots created by supported storage systems without affecting the production VMs or hosts. Both transport modes can improve backup performance, reduce backup window, and minimize impact on the production environment.

To design a solution that meets the needs and requirements of Veeam University Hospital, you need to gather some information during the discovery phase. This information will help you to understand the current state of the environment, the goals and expectations of the stakeholders, and the constraints and challenges of the project.

According to the Veeam Backup & Replication Best Practice Guide1, some of the information that is necessary for designing a solution and must be gathered during discovery are:

* Operating systems used to run the workloads. This information will help you to determine the compatibility and supportability of the workloads with Veeam products and features, as well as the licensing and configuration requirements.

* Allowed backup windows. This information will help you to plan and schedule the backup jobs according to the availability and performance of the workloads, as well as the service level agreements (SLAs) and recovery point objectives (RPOs) of the organization.

* Amount of used disk space. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the type and size of the data.

To design a solution that meets the offsite copies and archives requirements for Veeam University Hospital, you need to clarify some of the assumptions and expectations of the customer. This will help you to avoid any misunderstandings or conflicts that may arise during the implementation or operation of the solution.

According to the Veeam Backup & Replication Best Practice Guide, offsite copies and archives are two different concepts that serve different purposes. Offsite copies are backups that are stored in a different location than the primary backup storage, and are used for disaster recovery purposes. Archives are backups that are stored for a longer retention period than the regular backups, and are used for compliance or historical purposes.

Based on these definitions, the requirement that needs additional information to help clarify the customer expectation is C. Backups must take advantage of public cloud storage for long term archival purposes.

To design a solution that meets the virtual infrastructure requirements for Veeam University Hospital, you need to collect some information during the discovery phase. This information will help you to understand the configuration and performance of the VMware clusters, the size and type of the data, and the backup and recovery objectives.

According to the Veeam Backup & Replication Best Practice Guide, some of the information related to the virtual infrastructure that is missing and must be collected during the discovery phase are:

* Local area network speed. This information will help you to determine the network bandwidth and throughput that are available for backup and replication traffic, as well as the impact of backup and replication activities on the network performance and latency.

* Size of the source data set. This information will help you to estimate the backup storage requirements, as well as the backup compression and deduplication ratios, based on the size and type of the data.

Therefore, the correct answer is A and D.

To design a solution that meets the NAS environment requirements for Veeam University Hospital, you need to collect some information during the discovery phase. This information will help you to understand the characteristics and performance of the NAS systems, the size and type of the data, and the backup and recovery objectives.

According to the Veeam Backup & Replication Best Practice Guide, some of the information that you should collect from the customer about the data stored on the NAS per site are:

* Total number of files (in millions) to be backed up. This information will help you to estimate the backup storage requirements, as well as the backup performance and scalability, based on the number and distribution of files.

* Largest file size. This information will help you to determine the optimal backup block size and alignment, as well as the backup compression and deduplication ratios, based on the size and type of files.

To design a disaster recovery solution that meets the needs and requirements of Veeam University Hospital, you need to identify some information during the discovery phase. This information will help you to understand the scope and scale of the replication and failover processes, the network and storage resources and limitations, and the recovery time objectives and recovery point objectives.

According to the Veeam Backup & Replication Best Practice Guide, some of the information that is necessary to design the disaster recovery solution and must be identified during discovery are:

* The number of virtual machines to be replicated. This information will help you to determine the number and size of the replication jobs, as well as the replication performance and scalability, based on the number and type of virtual machines.

* The available bandwidth between locations. This information will help you to estimate the network bandwidth and throughput that are available for replication traffic, as well as the impact of replication activities on the network performance and latency.

* Which sites will be the source of replication and which sites will be the targets for recovery. This information will help you to plan and configure the replication infrastructure, such as the proxy servers, repository servers, WAN accelerators, and failover plans, based on the source and target locations.
