Step 6. Specify Object Storage Container

At this step of the wizard, specify object storage container and folder where you want to save your data.

  1. From the Container drop-down list, select an Azure container.

Make sure that the container you want to use to store your data was created in advance; Veeam Backup for Microsoft 365 does not support creating new containers.

  1. In the Folder field, select a cloud folder to which you want to map your object storage, and which will be used to store offloaded data.

To select a folder, click Browse and either select an existing folder or create a new one by clicking New Folder.

For more information on how data is stored, see Object Storage Structure.

  1. Select the Make backup copies immutable for the entire duration of their retention policy check box to enable protection of backup copies against accidental data deletions, malware activity and modifications that may be performed by 3rd party applications. For more information about immutability, see Immutability.


If you do not want to use immutability, make sure that Versioning is not enabled for the Microsoft Azure Blob storage account that you want to use.

  1. Click Advanced if you want to configure storage consumption limitations.
