Based on the requirements, what should be factored into the physical design when implementing backup copy jobs between sites?

Ensure that the repositories leveraged have CPUs that support hardware encryption offload.

Configure Veeam Backup Enterprise Manager on the same virtual machine as your Veeam Backup & Replication server

Use physical servers for the Veeam backup proxies at each site

Use virtual servers on separate ESXI host the Veeam backup proxies

説明
The factor that should be considered in the physical design when implementing backup copy jobs between sites is to use physical servers for the Veeam backup proxies at each site. A Veeam backup proxy is a data mover component that performs data processing and transfer tasks for backup and backup copy jobs. A physical server is preferred over a virtual server for better performance, reliability, and isolation. A physical server can also leverage hardware encryption offload to reduce CPU load and network traffic encryption to secure data in transit.

質問22
When talking to someone who works for the hospital, they mention they are working on a projectwith a major cloud provider that does not currently support immutability. After further conversations, the customer has decided that they would like daily immutable backups to be sent off-site. Which of the following is the best option to still satisfy the requirements for off-site immutable backups?

Backup copy to a hardened repository.

Backup copy to repository on a Cloud-based Windows Instance that scheduled to power off outside the backup window.

Set up capacity tier with object that supports immutability at the primary site.

Back up to tape and leverage a service to rotate tapes off-site weekly.

説明
To design a solution that meets the requirements for off-site immutable backups for Veeam University Hospital, you need to consider some of the options and features that Veeam products and features offer. This will help you to ensure the security and integrity of your backup data, as well as the compatibility and supportability of the cloud provider that does not currently support immutability.
According to the Veeam Backup & Replication Best Practice Guide, immutability is a feature that prevents backup files from being deleted or modified by anyone until the specified retention period expires.
Immutability can be achieved by using S3 Object Lock or Hardened Repository, which are two different solutions that Veeam Backup & Replication supports.
Based on this definition, the best option to still satisfy the requirements for off-site immutable backups is A.
Backup copy to a hardened repository.
This option means that:
*The backup copy is a type of job that allows you to create and maintain copies of your backup data on a secondary backup repository. You can use backup copy jobs to send your backup data off-site, as well as to apply different retention settings and policies.
*The hardened repository is a solution that allows you to add a hardened repository based on a Linux server to your backup infrastructure. You can use hardened repository with Veeam Backup & Replication to make your backups immutable on-premises or off-site.
*The backup copy to a hardened repository can be configured and managed by Veeam Backup & Replication, regardless of the cloud provider that does not currently support immutability. You only need to deploy and connect a Linux server with a hardened repository in the cloud environment, and then use it as a target for your backup copy jobs.

Yearly growth rate

Change rate

Datastore type

Operating system type

質問24
What information is necessary for designing a solution and must be gathered during discovery? (Choose 3) Size of the backup create by the incumbent backup solution.

Operating systems used to run the workloads.

Allowed backup windows.

Size of IT team.

Amount of used disk space.

Amount of disk space provisioned.

説明
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.

質問25
During discovery, it is determined that a group of MSSQL systems are running in an Always-On cluster and sensitive to virtual machine stun. How should these systems be configured for backups?

Deploy Veeam agents configured for failover clustering.

Perform a regular virtual machine backup without application aware processing.

Enable application aware processing on the virtual machine backup job.

Deploy Veeam agents in server mode.

説明
The best way to configure backups for a group of MSSQL systems running in an Always-On cluster and sensitive to virtual machine stun is to deploy Veeam agents configured for failover clustering. Veeam agents can provide application-aware processing and transaction log backup for MSSQL servers, as well as support for failover clustering and cluster shared volumes. Veeam agents can also reduce the impact of virtual machine stun by performing backups at the guest OS level, without using VMware snapshots.

質問26
How would you configure replication with seeding, considering this deployment will have a Veeam Backup Server in both the primary and secondary site?

On the Veeam Backup & Replication server at the primary site, create a backup job of the source machine from the primary site. At the secondary site import seeding data from this backup job. Create a replica job pointing to this backup job using re-mapping.

On the Veeam Backup & Replication server at the primary site, create a backup job and backup copy job sending data to the secondary site. At the secondary site, create a replica job pointing to therepository with the backup copy data.

On the Veeam Backup & Replication server at the primary site, create a backup job of the source virtual machine from the primary site. At the secondary site, create a replica job pointing to the repository with the backup job data.

On the Veeam Backup & Replication server at the secondary site, create a backup job of the source virtual machine from the primary site. At the secondary site, create a backup copy job pulling the data from the primary and create a replica job pointing to the repository with the backup copy data.

説明
Option C uses replica seeding to reduce the network traffic during the initial replication. By creating a backup job of the source VM at the primary site and pointing the replica job to that backup repository at the secondary site, Veeam Backup & Replication can restore the VM from the backup and synchronize it with the latest state of the source VM. Then it can use the restored VM as a replica2 Reference: Replica Seeding and Mapping – User Guide for VMware vSphere

質問27
During architecture planning, Veeam Life and Indemnity decides that recovery point objective of gold tier machines should change from one hour to three hours with daily retention set to seven days. What will be impact on the Veeam design?

Proxies will require fewer resources

More proxy servers will be required

Repositories will require more resources.

The Veeam database size will increase.

説明
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.

質問28
What information is missing form discovery?

What the current LAN bandwidth is at Fresno.

What backup transport mode is currently used.

What type of backup storage is currently used.

What the available bandwidth is between Fresno and Carson City.

説明
The information that is missing from discovery is what the available bandwidth is between Fresno and Carson City. This information is important for designing and sizing the backup copy jobs that need to run daily between the two sites. The available bandwidth can affect the backup copy performance, duration, and size.
For example, you can use the available bandwidth to estimate how much data can be transferred between the sites within the backup copy window. You can also use theavailable bandwidth to determine whether you need to use compression, deduplication, or WAN acceleration to optimize the backup copy traffic.

質問29
Which type of backup job will you need more informacion on to properly plan backup copy job settings later to make sure you are creating the required number of restore point per day offsite?

Bronze tier backup jobs

Silver tier backup jobs

Gold tier backup jobs

Laptop backup jobs

説明
The gold tier backup jobs have the most stringent recovery point objective (RPO) of one hour for image backup and 15 minutes for transaction log backup. This means that they need to run more frequently than the other backup jobs and create more restore points per day. Therefore, to properly plan the backup copy job settings, you will need more information on the gold tier backup jobs, such as the number of VMs, the size of backups, the change rate, the retention policy, and the bandwidth available for copying backups to the offsite location.

質問30
For any replicated virtual workloads, the data must not be more than one hour old. What could be a potential risk to the SLA for the offsite disaster recovery aspect of this requirement?

The quantity of network hops.

Data change rate.

Average virtual machine size

Local area network bandwidth.

説明
To design a disaster recovery solution that meets the requirement of having the replicated virtual workloads data not more than one hour old, you need to consider some of the potential risks and challenges that may affect the service level agreement (SLA) for the offsite disaster recovery aspect of this requirement. This will help you to ensure the availability and reliability of the replication and failover processes, as well as the recovery time objective (RTO) and recovery point objective (RPO) of the organization.
According to the Veeam Backup & Replication Best Practice Guide, one of the potential risks to the SLA for the offsite disaster recovery aspect of this requirement is B. Data change rate.
This risk means that:
*The data change rate is the amount of data that is modified, added, or deleted in a given time period. It is usually measured in percentage or megabytes per hour.
*The data change rate affects the replication performance and efficiency, as it determines how much data needs to be transferred and processed between the source and target sites.
*The data change rate also affects the replication frequency and consistency, as it determines how often and how accurately the replicas are updated and synchronized with the source workloads.
*The data change rate may vary depending on the type and activity of the workloads, such as database, file server, web server, etc. Some workloads may have a high data change rate, while others may have a low data change rate.
*The data change rate may exceed the available bandwidth or storage capacity between the source and target sites, which may result in replication failures, delays, or errors. This may compromise the SLA for the offsite disaster recovery aspect of this requirement, as it may cause the replicated virtual workloads data to be more than one hour old.
This risk has some implications for designing a solution with Veeam products and features, such as:
*The customer or a third-party vendor must monitor and measure the data change rate of the workloads that need to be replicated, as well as the available bandwidth and storage capacity between the source and target sites. This will help to plan and optimize the replication infrastructure, such as the proxy servers, repository servers, WAN accelerators, and failover plans, based on the data change rate.
*The customer or a third-party vendor must configure and adjust the replication settings and policies, such as the replication method, schedule, frequency, retention, compression, deduplication, etc., based on the data change rate. This will help to improve the replication performance and efficiency, as well as to meet the SLA for the offsite disaster recovery aspect of this requirement.

質問31
Based on customer recovery requirements, which component will help them meet their stated objectives?

Add a Windows server and enable encryption of backups to ensure alternative decryption capabilities.

Deploy and configure Enterprise Manager with RBAC policies.

Deploy Veeam Backup & Replication console and set RBAC policies to Administrator Role

Add a Windows and Linux server, enable indexing of backups and ensure authenticated users are configured to appropriate RBAC policies.

説明
The component that will help the customer meet their stated objectives of role-based access control (RBAC) and alternative decryption capabilities is Veeam Backup Enterprise Manager. Veeam Backup Enterprise Manager is a web-based interface that allows centralized management of multiple Veeam backup servers. It also provides RBAC policies that enable granular control over user permissions and access to backup data. For example, you can assign different roles to different users or groups based on their responsibilities and needs, such as backup administrator, restore operator, securityofficer, etc. Veeam Backup Enterprise Manager also provides password loss protection feature that enables authorized users to restore encrypted backups without entering passwords if they forget or lose them.

質問32
What information related to the virtual infrastructure is missing and must be collected during the discovery phase) (Choose 2)

Number of vSphere clusters

Backup window

Recovery time objective

Total of virtual machines

Number of scale-out Backup Repository extents currently used

説明
The number of vSphere clusters and the total of virtual machines are important information related to the virtual infrastructure that are missing and must be collected during the discovery phase. These information can help you estimate the backup performance, scalability, and resource requirements for the Veeam backup infrastructure. For example, you can use the number of vSphere clusters to determine how many Veeam backup servers and proxies you need to deploy and how to distribute the backup load among them. You can also use the total of virtual machines to calculate the total amount of data to be backed up, the storage space required, and the network bandwidth needed.

質問33
To demonstrate SLA compliance during audits and protection against exposure to personally identifiable information, which configuration would verify this is possible in the event of exposure?

Implement Veeam Backup & Replication servers at one location and leverage hardened repositories as a primary target with a backup copy to a second site.

Create secure restore to ensure malware-free backups.

Create a virtual lab environment and periodically perform staged restores with custom scripts.

Scan backups with Veeam ONE to remove personally identifiable information.

説明
The configuration that would verify the SLA compliance during audits and protection against exposure to personally identifiable information in the event of exposure is to create a virtual lab environment and periodically perform staged restores with custom scripts. A virtual lab is an isolated environment where you can run your backups or replicas without affecting the production environment. A staged restore is a process that allows you to run custom scripts on the restored data before publishing it to the production environment.
By using these features, you can demonstrate that your backups are recoverable and compliant with legal regulations, as well as remove or mask any sensitive data before restoring it.

質問34
You are examining the requirement: “If possible, the data written must be unchangeable to prevent ransomware attacks.” Which types of jobs do not support using immutability from S3 Object Lock or hardened repositories? (Choose two)

NAS backups

Linux Agent backup copy jobs

VMware backup jobs

Agent for Mac backups

説明
The types of jobs that do not support using immutability from S3 Object Lock or hardened repositories are NAS backups and Agent for Mac backups. These types of jobs do not have the option to enable immutability in their settings, unlike VMware, Hyper-V, Linux Agent, or Windows Agent backup jobs. Therefore, they cannot leverage the immutability feature of S3 Object Lock or hardened repositories to protect their backups from ransomware or malicious deletion.
References: [S3 Object Lock Immutability], [Hardened Linux Repository], [NAS Backup], [Agent for Mac]

質問35
Looking at the existing error, you suspect that most of the issues could be resolved with different repositories.
Assuming the repositories will be able to accomplish much higher throughput, what new issue might come up?

The bandwidth between sites might not be sufficient.

The repository space consumption could decrease

The production firewall could become a bottleneck

The increased backup speed could completely bring down production storage.

説明
If the repositories are able to accomplish much higher throughput, a new issue that might come up is that the bandwidth between sites might not be sufficient to support the backup copy jobs that need to run daily between Fresno and Carson City. This could cause the backup copy jobs to fail, take longer than expected, or consume too much network resources. Therefore, it is important to measure the available bandwidth between the sites and compare it with the backup copy data size and window. If the bandwidth is not sufficient, some possible solutions are to use compression, deduplication, or WAN acceleration to reduce the backup copy traffic.

質問36
When deciding on the design of the primary backup repository, which option best fits the requirements in the case study?

Dedupe appliance leveraging vendor API for access

Public cloud storage with S3 object-lock for immutability

Windows repository using ReFS integration, single-use credential and persistent VSS snapshot

Linux Repository using XFS integration, single-use credentials, and immutability

説明
The best option for the primary backup repository design that fits the requirements in the case study is a Linux Repository using XFS integration, single-use credentials, and immutability. A Linux Repository is a type of backup repository that uses a Linux server as a backup target. A LinuxRepository can leverage XFS integration to enable fast creation and transformation of synthetic full backups by using XFS file system features such as reflink and copy-on-write. A Linux Repository can also use single-use credentials to enhance security by generating unique credentials for each backup job session. A Linux Repository can also provide immutability and ransomware protection for backup files by using Linux access control mechanisms such as immutable flag or chattr command.
