 Use import to bring Redis compatible RDB files from any Redis server running in any cloud or environment, including Redis running on Linux, Windows, or any cloud provider such as Amazon Web Services and others. Importing data is an easy way to create a cache with prepopulated data. During the import process, Azure Cache for Redis loads the RDB files from Azure storage into memory and then inserts the keys into the cache.

-> Before beginning the import operation, ensure that your Redis Database (RDB) file or files are uploaded into page or block blobs in Azure storage, in the same region and subscription as your Azure Cache for Redis instance. For more information, see [Get started with Azure Blob storage](../storage/blobs/storage-quickstart-blobs-dotnet.md). If you exported your RDB file using the [Azure Cache for Redis Export](#export) feature, your RDB file is already stored in a page blob and is ready for importing.
