Establishing a Backup and Restoration Plan
Topic Last Modified: 2011-05-16
Creating a backup and restoration plan involves the following steps:
Developing the plan
Implementing the plan
Maintaining the plan
Developing a Backup and Restoration Plan
After you develop your backup and restoration strategy for Microsoft Lync Server 2010, use it to document a detailed backup and restoration plan. Your plan should clearly convey the priorities and requirements for backing up data and settings. You can use the information in Establishing a Backup and Restoration Strategy and the worksheets in Backup and Restoration Worksheets to facilitate documentation of your strategy. Your plan should also contain criteria for deciding when and how to restore service.
As you develop your plan, you need to consider and account for the following:
How you will recover servers on new hardware.
How you will recover services that require action on the part of multiple business areas or departments.
How you can acquire spare servers quickly.
The time it takes to recover by using your strategy.
Modify the backup and restoration procedures in this document, adding and deleting procedures as appropriate to reflect the servers and components in your deployment. You can also add appropriate details, such as the backup schedule, to the appropriate procedures to ensure that the information is not overlooked.
It is good practice to create scripts for as many steps as possible to ensure the quality and reproducibility of procedures.
In your plan, specify who is responsible for reviewing the plan, who is responsible for testing and validating any new procedures or tools, and who must approve changes to the plan and related procedures.
To ensure that your backup and restoration plan fully meets all established goals and priorities, obtain the approval of the appropriate business and technical decision makers in your organization before you implement the plan.
Implementing the Backup and Restoration Plan
Implementing a backup and restoration plan requires the following:
Testing and validating the plan
Communicating the plan
Validating backup and restoration operations
Testing and Validating the Plan
The procedures in this document have been tested and validated in a lab environment. To ensure that these or any other procedures work in your environment, you should test and validate each procedure you intend to implement. Complete testing and validation before you submit your plan for final approval.
Communicating the Plan
Your backup and restoration plan should clearly describe who implements procedures and step-by-step instructions for carrying out the procedures. You should ensure that everyone responsible for any aspect of backup and restoration understands the plan, how it is to be implemented, and what their role is. This includes all implementation requirements for the following:
Pool and server backup
Restoration of service
Pool and server backup
The backup and restoration plan should include all information required to complete backup procedures on an ongoing basis. The primary information to be communicated to responsible team members includes the following:
Team or person (specified as an individual or role) responsible for backing up each server
Specific schedules for backing up each server
Backup locations for each type of data (settings, database, and file shares)
Backup procedures to be used, including the tools required to complete each procedure
Information required to complete backups, as covered in Backup and Restoration Worksheets.
Validation methods to be used to ensure that data and settings are appropriately backed up and available for restoration, which can include periodic audits and test restorations.
Restoration of service
The backup and restoration plan should include all information required to restore service, in case one or more servers suffers a loss that makes service unavailable. The primary information to be communicated to responsible team members includes the following:
Team or person (specified as an individual or a role) that is responsible for determining when restoration of service is required and the procedures to be used to restore service, and also the team or person responsible for implementing procedures for each restoration scenario.
Criteria for determining which restoration procedures are most appropriate for a specific situation.
Time estimates for restoration of service in each restoration scenario.
Restoration procedures to be used, including the tools required to complete each procedure.
Information required to restore data and settings. Worksheets are provided in Backup and Restoration Worksheets.
Validating Backup and Restoration Operations
After completing initial backup efforts in your production environment and at specified intervals (as covered in your backup and restoration plan), you should verify the following:
Backups are occurring as required.
Backed up data and settings are accessible.
Restoration procedures can be performed within the times specified in the backup and restoration plan and the results meet all business requirements, as specified in your backup and restoration plan.
Backup worksheets have been completed and verified, and they are stored in a secure location. These worksheets are provided in Backup and Restoration Worksheets.
Restoration procedures have been tested and verified to work as expected, as specified in your backup and restoration plan.
Maintaining the Backup and Restoration Plan
A Lync Server 2010 topology is a dynamic environment that changes with your organization. Reassess your backup and restoration plan as your organization changes, and review it periodically to ensure that it continues to meet the needs of your business.
