Blob storage


Blob storage has the advantage of better scalability. When your Sitefinity Cloud database becomes too big, handling and restoring it may become time consuming. In this case, it is best to use Blob storage for your media files.

Sitefinity Cloud uses Azure Blob storage provider, which is an implementation of a cloud blob storage provider that stores the binary blob data of Sitefinity Cloud library items on Azure storage. 
For more information, see Microsoft documentation » Introduction to Azure Blob storage.

PREREQUISITES: You must have purchased Sitefinity Cloud Blob storage add-on. 

Blob size

The storage allocated for the blob is 1 TB for all of your environments. To calculate how much storage you will have per environment, you have to divide 1 TB by the number of your environments, including the Development environment. You can purchase more storage, if required.


To accommodate for blob storage, Sitefinity Cloud has added an Azure storage account. In this account, there are different blob storage containers – one for each environment. Each environment is configured to work with the respective blob container.

There are three different case in which media file blobs are synchronized between environments:

  • DB.RestoreBetweenEnvironments pipeline
    This pipeline is used to restore the database from one environment to another. As part of the operation, the blobs in the container on the target environment are replaced with the blobs in the container on the source environment.
  • DB.Export pipeline
    This pipeline is used to export a database backup from the cloud environments that can be used for local development purposes. As part of the operation, the blob container from the cloud environment is synced to the blob container used for the local development environment. In this process, media file blobs are merged, where blobs that are located only in the container for the local development environment are not deleted. 
  • SiteSync
    Sitefinity SiteSync has out-of-the-box functionality that syncs blob items between different blob containers.
    When you sync content from Content staging to Production, it automatically syncs blob items. If an item is present on Production, but not on Content staging, it is deleted from the Production environment.

The following chart demonstrates how blob containers are synchronized:


Use the Blob storage add-on

After you have purchased the Blob storage add-on, it is automatically set up and you can move any library from database to blob storage or create a new library that is persisted in the blob.

For more information about changing the storage provider of a library, see Libraries.
