 If an Azure Cache for Redis cache failure occurs, data loss is possible when nodes are down. [Redis persistence](https://redis.io/topics/persistence) allows you to persist the data stored in cache instances. If there's a hardware failure, the cache instance rehydrates with data from the persistence file when it comes back online.

 ### Prerequisites
 
 - To create and add persistence to Azure Redis caches, you need write access and permissions to create Premium or Enterprise-level caches in an Azure subscription.
-- For Premium-tier caches, you need an [Azure Storage account](/azure/storage/common/storage-account-create) in the same region as your cache to store the cache data. If you use [managed identity](cache-managed-identity.md) as an authentication method, you can use a storage account in a different subscription than your cache.

If you use [managed identity](cache-managed-identity.md) as the authentication method, you can use a storage account in a different subscription than your cache.
 - For the Azure PowerShell procedures, you need [Azure PowerShell installed](/powershell/azure/install-azure-powershell), or use [Azure Cloud Shell](/azure/cloud-shell/get-started/ephemeral?tabs=powershell) with the PowerShell environment in the Azure portal.
 - For the Azure CLI procedures, you need [Azure CLI installed](/cli/azure/install-azure-cli), or use [Azure Cloud Shell](/azure/cloud-shell/get-started/ephemeral?tabs=azurecli) with the Bash environment in the Azure portal.
