Backing up Azure Blobs

As customers adopt the Microsoft Azure platform, the need to backup Azure Blobs is becoming increasingly important. That’s because Azure Blobs are used by both the Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) components of Microsoft Azure. In fact, Azure Blobs are also becoming more popular with local software applications that need a central location to store configuration information and application logs. Since Blobs are a form of data, there is a need to back them up.

Until now, the way to backup Azure Blobs was to copy the files on local hard drives, which many third party tools currently provide. However Azure Blobs contain additional information that files can’t carry, such as custom metadata, HTTP properties, and Access Control List (ACL) details providing security information on those blobs. But Azure Blobs are not the only components that need to be backed up: Azure Blob Containers are also important. They are the equivalent of directory structures, and also carry metadata and ACL information. Existing third party tools do not provide a mechanism to save this additional information.

I created a free utility called Enzo Cloud Backup, version 3, now available for download ( This tool allows you to perform backup and restore operations on Azure Blobs (in addition to Azure Tables and Azure SQL Database). It is designed to handle a very large number of blobs and containers. In addition, an API is also available at no charge so that you can programmatically initiate backup and restore operations.

The free edition provides all the features of the advanced edition, but is limited in the number of backups that can be performed monthly. Give it a try; you will be surprised by how easy it is to use. And if you have some feedback, please send them to me!
