About backup of azure data lake storage gen2

Hi There!

Please tell me how to get a backup of azure data lake storage gen2 online (without interrupting the process on the target resource).
We would like to restore the data in azure data lake storage gen2 in case we accidentally delete the data in azure data lake storage gen2.
I have checked the documentation below and thought that BlobStorage's snapshot taking feature would be useful, but I would like to know if there is any other way to do this.

    Hello @Yuta Harada ,

    For Azure Data Lake Gen2 Data Protection, you can use Enable Soft delete for blobs/containers to restore the deleted data.


    What is Soft Delete?

    Blob soft delete protects an individual blob, snapshot, or version from accidental deletes or overwrites by maintaining the deleted data in the system for a specified period of time. During the retention period, you can restore a soft-deleted object to its state at the time it was deleted. After the retention period has expired, the object is permanently deleted.

    How to enable soft delete?

    Go to the ADLS gen2 storage account, under Data management, select Data Protection and enable Recovery options as shown below:


    Now try to delete any folder or a file under container.


    Now lets try to restore the file which we deleted. Select the file to undelete.

    Note: Make sure select the Show deleted objects to show the deleted files.


    Hope this will help. Please let us know if any further queries.
