Use the xbcloud binary with Microsoft Azure Cloud Storage¶
The xbcloud binary adds support for the Microsoft Azure Cloud Storage using the REST API.
Options¶
The following are the options, environment variables, and descriptions for uploading a backup to Azure using the REST API. The environment variables are recognized by xbcloud, which maps them automatically to the corresponding parameters:
| Option name | Environment variables | Description |
|---|---|---|
| –azure-storage-account=name | AZURE_STORAGE_ACCOUNT | An Azure storage account is a unique namespace to access and store your Azure data objects. |
| –azure-container-name=name | AZURE_CONTAINER_NAME | A container name is a valid DNS name that conforms to the Azure naming rules |
| –azure-access-key=name | AZURE_ACCESS_KEY | A generated key that can be used to authorize access to data in your account using the Shared Key authorization. |
| –azure-endpoint=name | AZURE_ENDPOINT | The endpoint allows clients to securely access data |
| –azure-tier-class=name | AZURE_STORAGE_CLASS | Cloud tier can decrease the local storage required while maintaining the performance. When enabled, this feature has the following categories: Hot - Frequently accessed or modified data Cool - Infrequently accessed or modified data Archive - Rarely accessed or modified data |
Test your Azure applications with the Azurite open-source emulator. For testing purposes, the xbcloud binary adds the --azure-development-storage option that uses the default access_key and storage account of azurite and testcontainer for the container. You can overwrite these options, if needed.
Usage¶
All the available options for xbcloud, such as parallel, max-retries, and others, can be used. For more information, see the xbcloud binary overview.
