Immutable storage with versioning adds up the capacity to set an immutable policy on the container or object level. The service also allows for the immutable protection of all past and present versions of any blob. 

While in a WORM state, data cannot be modified or deleted for a user-specified interval. Immutable storage for Azure Blob storage supports two kinds of immutability policies - time-based retention policies, and legal hold policies.

In a time-based retention policy, you can set policies to store data for a specified interval. While, with a legal hold you can make data non-erasable and non-modifiable until the legal hold is explicitly cleared.
