With virtualization steadily stepping out of the test / development environment and entering mainstream data centers to support business and first-level applications, customers are facing new challenges related to virtual server and virtual machine (VM) data protection and management. Technology solution providers who are familiar with these challenges are fully prepared and hope to become important consultants that customers trust.

The following five principles have a certain reference and guidance role for solution providers to help them establish leading virtual server data protection practices, so that customers can more easily and quickly deploy virtual servers.

1. Choose a backup solution that can optimize the performance of the virtual platform

The common advantages of virtualization and cloud-based infrastructure are obvious, such as workload balancing cost savings, application flexibility, and less physical footprint. However, the need to reserve resources for data management and protection is growing rapidly. Storage and backup teams are often required to use limited computer, network and storage resources to protect the growing large-scale data to be stored. The amount of data stored in virtual machines has grown rapidly, creating a situation that is difficult to maintain. This will cause the backup window to be damaged, the performance of the front-end application to be degraded, or even to meet the service level requirements.

End users need a backup solution that can provide performance, manageability, and scalability for mission-critical applications on their virtual servers to support these important applications as needed, and ensure that data is fully protected and easy to recover . This shows that the solution provider needs to understand the individual requirements and dynamic characteristics of the customer's virtual environment and provide corresponding modern solutions to minimize the impact on front-end applications. By deploying snapshots and replication tools, solution providers can implement data protection strategies that can reduce the time required to protect the largest data storage and the most demanding workloads to a few minutes while reducing the impact on front-end applications . The ideal solution is to perfectly combine the efficiency advantages of snapshots with backup directories that greatly simplify recovery operations.

2. Ensure application-aware data protection

As more and more critical applications are virtualized, it is necessary to provide these applications with the same level of protection and recovery as they do on purely physical servers. Modern data centers need to adopt agreed backup and recovery functions to ensure the maximum running time of critical applications running on virtual machines. This key depends on the selection of appropriate data and information management solutions, such solutions must provide continuous application-aware data protection, but also to adapt to the constraints of a highly integrated virtualization environment. However, not all virtual server backup solutions are the same, and their difference lies in the details. Application-aware data protection is not as easy as simply saying "we have" or "we use VSS (Volume Shadow Copy Service)"-for most deployments, this is not enough. Application-aware data protection must include features such as business log truncation, seamless search, and single application recovery to ensure that images running on virtual machines that are consistent with applications are recovered at a certain point in time. This will bring confidence in virtualizing more applications in order to realize the advantages of the virtual platform faster. Solution providers need to understand their customers ’requirements for application protection and recovery, and provide matching and optimized solutions.

3. Integrated data replication technology to meet the service level requirements of critical applications

Data is growing and changing rapidly, and relying on backups 24 hours ago is no longer sufficient to meet the needs of data growth. As companies deploy more and more critical applications in virtual server environments, they need to achieve near real-time recovery-not from backup copies from the previous night. For example, many Exchanges deploy a four-hour recovery node objective (RPO), and many database applications have a one-hour recovery node objective. Traditional backup simply cannot meet these service level agreements (SLAs). Creating frequent recovery nodes without affecting production activities is a huge challenge.

Solution providers need to integrate virtual machine snapshots and data replication technologies so that customers can quickly, efficiently, and economically create copies of production data for recovery. Advanced features, such as data encryption, compression, and bandwidth limitation, can ensure that data is protected while optimizing the use of existing network bandwidth. Data copies are available for immediate access to create multiple recovery nodes and perform traditional backups without affecting server performance or create a second copy in another location for disaster recovery. The result of this is that customers can keep their business running with minimal disruption and data loss.

4. Granular data recovery

To speed up data recovery, customers need a data integration method that restores small particles at the volume, file, or application object level. Traditional methods need to go back to the entire virtual machine database (such as VMDK) and search the entire content to find a single file, such as an email, which is very time-consuming and takes up a lot of resources. At present, many new methods are available, but they may require a second operation to obtain the required small-grain data / files. This will increase the extra processing time in the data protection process, and the risks will follow. Therefore, only a single backup and restore operation can achieve data particle recovery solution is currently the most ideal.

5. Provide automatic management tools to enhance virtual machine protection

Administrators can now deploy new virtual machines within minutes. This ease of implementation has led to the rapid spread of virtual machines, making tracking new virtual machines and manually applying data protection strategies very time-consuming. Important virtual machines may never be backed up after being created, which will bring greater business risks.

In-depth management program integration and advanced automation features will help customers protect hundreds of virtual machines and easily expand to thousands of virtual machines in minutes. Advanced features like automatic virtual machine protection automatically discover new virtual machines and add them to data protection strategies in obvious ways.
