Relocate Azure Recovery Vault and Site Recovery to another region

This article shows you how to relocate Azure Recovery Vault and Site Recovery when moving your workload to another region.

Существуют различные причины, по которым может потребоваться переместить существующие ресурсы Azure из одного региона в другой. Возможно, вам потребуется:

• Воспользуйтесь новым регионом Azure.
• Развертывание функций или служб, доступных только в определенных регионах.
• Отвечайте требованиям к внутренней политике и управлению.
• Align with company mergers and acquisitions
• Соответствуйте требованиям к планированию мощностей.

One of the related resources you might want to relocate when you relocate your Azure VMs is your Recovery Services vault configuration.

There's no first-class way to move an existing Recovery Services vault configuration from one region to another. This is because you configured your target region based on your source VM region. When you decide to change the source region, the previously existing configurations of the target region can't be reused and must be reset. This article defines the step-by-step process to reconfigure the disaster recovery setup and move it to a different region.

• Copy the details replication goal from the SourceRecovery Services vault.

• Copy the details replication policy from the Source Recovery Services vault with the critical details such as:

  • RPO threshold defines how often recovery points are created.
  • Recovery point retention specifies how longer each recovery point is retained.
  • App-consistent snapshot frequency specifies how often app-consistent snapshots are created.

• Скопируйте внутренние ресурсы или параметры Azure Resource Vault.

  • Перенастройка сетевого брандмауэра
  • Alert Notification.
  • Move workbook if configured
  • Перенастройка параметров диагностики

• Список всех зависимых ресурсов Хранилища служб восстановления. Наиболее распространенными зависимостями являются:

  • Виртуальная машина Azure
  • Общедоступный IP-адрес
  • Виртуальная сеть Azure
  • Хранилище служб восстановления Azure

• Determine network bandwidth need vs. RPO assessment

  • Расчетное значение пропускной способности, необходимой для разностной репликации.
  • Пропускная способность, которую может получить Site Recovery из локальной среды в Azure.
  • Количество виртуальных машин, которое можно включить в пакет, на основе расчетного значения пропускной способности для завершения начальной репликации в указанный промежуток времени.
  • RPO that can be achieved for a given bandwidth
  • Влияние на желаемую RPO при выделении низкой ширины пропускания.

• As it's a relocation of Recovery service vault, you must cross check the permission requirement in the current VMware vCenter server/VMware vSphere ESXi host during profiling.

• Make sure that you remove and delete the Site Recovery configuration before you try to move the Azure VMs to a different region.

  Примечание.

  If your new target region for the Azure VM is the same as the Site Recovery target region, you can use your existing replication configuration and move it. Follow the steps in Move Azure IaaS VMs to another Azure region.

• Ensure that you're making an informed decision and that stakeholders are informed. Your VM won't be protected against disasters until the move of the VM is complete.

Identify Azure Site Recovery dependencies

We recommend that you do this step before you proceed to the next one. It's easier to identify the relevant resources while the VMs are being replicated.

For each Azure VM that's being replicated, go to Protected Items>Replicated Items>Properties and identify the following resources:

• Целевая группа ресурсов
• Cache storage account
• Target storage account (in case of an unmanaged disk-based Azure VM)
• Target network

Disable the existing disaster recovery configuration

1. Go to the Recovery Services vault.
2. In Protected Items>Replicated Items, right-click the machine and select Disable replication.
3. Repeat this step for all the VMs that you want to move.

Удаление ресурсов

1. Go to the Recovery Services vault.
2. Выберите команду Удалить.
3. Delete all the other resources you previously identified.

Relocate Azure VMs to the new target region

Follow the steps in these articles based on your requirement to relocate Azure VMs to the target region:

• Перенос виртуальных машин Azure в другой регион
• Перенос виртуальных машин Azure в Зоны доступности

Set up Site Recovery based on the new source region for the VMs

Configure disaster recovery for the Azure VMs that were moved to the new region by following the steps in Set up disaster recovery for Azure VMs.
