# Azure Storage Backend
|
|
|
|
|
|
|
|
|
|
|
|
The Azure storage backend is used to persist Vault's data in an
|
|
|
|
|
|
[Azure Storage Container][azure-storage]. The storage container must already
|
|
|
|
|
|
exist and the provided account credentials must have read and write permissions
|
|
|
|
|
|
to the storage container.
|
|
|
|
|
|
|
|
|
|
|
|
- **No High Availability** – the Azure storage backend does not support high
|
|
|
|
|
|
availability.
|
|
|
|
|
|
|
|
|
|
|
|
- **Community Supported** – the Azure storage backend is supported by the
|
|
|
|
|
|
community. While it has undergone review by HashiCorp employees, they may not
|
|
|
|
|
|
be as knowledgeable about the technology. If you encounter problems with them,
|
|
|
|
|
|
you may be referred to the original author.
