If you are looking to optimize their storage costs on Azure Blob storage. With the increasing amount of data being stored in the cloud, it’s important to keep track of the size of each Blob and identify which ones are taking up the most storage. This is where the guide comes in – it provides a step-by-step process on how to use Cloud Storage Manager to find the largest Azure Blobs in your environment.

By identifying the largest Blobs, you can take steps to optimize your storage costs, such as deleting unnecessary data or moving data to a more cost-effective storage tier. Whether you’re new to Azure Blob storage or an experienced user, this guide is a helpful resource for optimizing your storage costs.

Recently we had one of our clients inform us that he used Cloud Storage Manager to find which were the largest Blobs in his Azure Storage Containers

Here is a quick run down to show one of the many reports on your Azure Blob consumption that you can run with Cloud Storage Manager.

Which are my largest Azure Blobs?

If you want to find out which BLOBs in your environment are the largest, or consuming the most storage, the easiest and simplest method by far is to use Cloud Storage Manager.

Once you’ve allowed Cloud Storage Manager to scan your environment, you have a few options to get this information.

The Top 100 BLOBs tab will give you a list of the top 100 largest BLOBs in your environment. It will also show you which Subscription, Storage Account, Container the BLOB resides in and of course its name. Not only that but it will tell you the object tier, whether that is hot, cool or archive, the size of the Azure BLOB, when it was created and when it was last modified.

Have a look at the screenshot to get a clearer picture.

In the bottom right corner you will also see how much overall storage your largest 100 BLOBs are consuming. In our example, we can see that our largest 100 BLOBs are consuming 102GB. Of course, this is just our lab environment so in a real production environment this could be hundreds of TB or PB!

You may also export this data into a spreadsheet by selecting the Reports tab and selecting the “List the top 100 BLOBs” report.

Right click on the report and select “Run Report” to view the data in an exportable table format that you can see in Microsoft Excel. 

The export includes all relevant information including the Azure Subscription, Azure Storage Account, the Container the Blob resides in, the name of the Azure Blob itself, what storage tiering the Blob is in, the date created, last modified and finally it’s size.
