You can protect a variety of Azure Function Apps and Azure serverless services such as Web Apps. This feature allows you to easily failover your PaaS serverless and App services, and enhances flexibility in reprovisioning applications.
Cloud Rewind backs up PaaS serverless and App services using a protection policy. This is done by consistently storing deployment images or code along their configurations in a storage account, both locally and remote region. During misdeployments and unforeseen disasters, you can recreate your serverless and web apps to reflect the latest configurations and the most up-to-date code or image that you initially deployed.
To create an Azure Serverless Cloud Assembly in Cloud Rewind, follow the below steps:
In General Information,
- Enter the Cloud Assembly name and description
- Select the Cloud Connection for which the resources have to be protected
- Choose the desired primary region from the list of operational regions
- For cross-region recovery, enable "Allow cross-region recovery" option
- Select the desired recovery region from the list of operational regions
In Resources,
- Choose the serverless resource groups from the list to be protected and add the selected resource group
In Protection strategy,
- Under Service Type (DISK), specify the Resource Group where the disk backups should be stored for both the primary and recovery regions
- Under Service Type (App Service/ Function App), specify the Storage account where your Serverless backups need to be stored. The entered storage account should be present in the respective region.
Note
Please avoid using your existing storage account, this might cause accidental backup deletion.
In Protection Policy,
- Select a protection policy to protect the resources
- Protection policy can be used to define the time at which the snapshot has to be taken and the number of snapshots to be retained using a retention count
- A policy template can be created to fit the protection needs best
- To create a new protection policy template, click here
- The policy can be activated as by the scheduled policy, immediately triggering one policy or by delaying to the specific time
In Review,
- Review the general information, resource information, and the protection policy details provided
- Edit the details if required and proceed to finish and create a Cloud Assembly
Note
- Cloud Rewind protects only configuration for App Service or Function App which is running in consumption mode
- If an App Service or Function App added under Cloud Rewind protection has a pre-configured Azure backup. Those backups will be overridden by Cloud Rewind new backup frequency.
