Use the xbcloud binary with Microsoft Azure Cloud Storage¶
Implemented in Percona XtraBackup 8.0.27-19, 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.
