To design a solution that meets the needs and requirements of Veeam University Hospital, you need to consider some of the risks and challenges that may affect the success and quality of the project. This will help you to identify and mitigate any potential issues or errors that may arise during the implementation or operation of the solution.
According to the Veeam Backup & Replication Best Practice Guide, a risk is a factor that may negatively impact the performance, reliability, security, or functionality of the backup and replication solution. A risk may be caused by internal or external factors, such as technical limitations, environmental constraints, human errors, etc.
Based on this definition, one of the possible risks for this project is C. Data must be replicated with one-hour recovery point objective.
This risk means that:
* The recovery point objective (RPO) is a business requirement that defines the maximum acceptable amount of data loss in case of a disaster or failure. It is measured in time units, such as minutes, hours, or days.
* The data replication is a technical solution that allows you to create replicas of your running workloads on another host or site. It is used for disaster recovery purposes, as it enables you to quickly fail over and fail back in case of a disaster.
* The one-hour RPO is a challenging and demanding requirement that may be difficult to achieve or maintain, depending on various factors, such as the data change rate, the available bandwidth, the replication frequency, etc.
* The one-hour RPO may also conflict or contradict with other requirements or expectations, such as the backup window, the backup retention, the backup storage capacity, etc.
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 between 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 one-hour RPO. This will help to improve the replication performance and efficiency, as well as to meet the RPO requirement.
* The customer or a third-party vendor must test and verify the replication results and processes, as well as perform regular failover and failback drills. This will help to ensure the reliability and consistency of the replicas, as well as to validate and improve the RPO achievement.
