Immutable storage with versioning for Blob Storage is now generally available
Published date: 08 December, 2021
Immutable storage with versioning for Blob Storage is now generally available. Immutable storage provides the capability to store data in a write once, read many (WORM) state. Once data is written, the data becomes non-erasable and non-modifiable, and you can set a retention period so that files can't be deleted until after that period has elapsed. Additionally, legal holds can be placed on data to make that data non-erasable and non-modifiable until the hold is removed.
Immutable storage with versioning adds the capability to set an immutable policy on the account, container, or object level. It also allows for the immutable protection of all past and current versions of any blob.
To learn more, please read the documentation on immutable storage with versioning.
Immutable storage with versioning policies and legal holds are free of charge. Storage usage and transactions will be billed as normal. To learn more about pricing, visit the Azure Storage Blobs Pricing | Microsoft Azure.
