Veeam Agent will use the compliance retention mode for each uploaded object.For more information, see How Backup Immutability Works and Block Generation. The effective immutability period consists of the user-defined immutability period and the block generation period automatically appended by Veeam Agent.Ĭonsider the following about backup immutability: For more information, see Microsoft Azure documentation. You must enable blob versioning and version-level immutability support in the storage account.
