Azure Data Lake Storage immutable storage is now in preview
Published date: June 30, 2020
Immutable storage for Azure Data Lake Storage is now available in preview. 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.
To learn more, please read the documentation on immutable storage.
This preview is currently available in Canada Central, Canada East, France Central, and France South. To enroll in the preview, complete this form.
Immutable storage 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 Data Lake Storage pricing page.
