-[Redis persistence](https://redis.io/topics/persistence) allows you to persist data stored in cache instance. If there's a hardware failure, the cache instance is rehydrated with data from the persistence file when it comes back online. The ability to persist data is an important way to boost the durability of a cache instance because all cache data is stored in memory. Data loss is possible if a failure occurs when cache nodes are down. Persistence should be a key part of your [high availability and disaster recovery](high-availability.md) strategy with Azure Managed Redis.

The RDB/AOF persisted data files can neither be accessed by users nor imported to a new or existing cache. To move data across caches, use the _Import and Export_ feature. For more information, see [Import and Export data in Azure Managed Redis](how-to-import-export-data.md).

 To generate any backups of data that can be added to a new cache, you can write automated scripts using PowerShell or Azure CLI that export data periodically.

 - The managed disk holding persisted data files is encrypted using Microsoft managed keys (MMK) by default, but customer managed keys (CMK) can also be used. For more information, see [managing data encryption](#managing-data-encryption).
