 ### Is soft delete available for virtual machine disks?  
 
-Soft delete is available for both premium and standard unmanaged disks, which are page blobs under the covers. Soft delete will only help you recover data deleted by **Delete Blob**, **Put Blob**, **Put Block List**, **Put Block** and **Copy Blob** operations. Data overwritten by a call to **Put Page** is not recoverable.

 An Azure virtual machine writes to an unmanaged disk using calls to **Put Page**, so using soft delete to undo writes to an unmanaged disk from an Azure VM is not a supported scenario.

-Blob versioning and blob soft delete work together to provide you with optimal data protection. For more information about blob soft delete, see [Soft delete for Azure Storage blobs](storage-blob-soft-delete.md).
+Blob versioning and blob soft delete work together to provide you with optimal data protection. When you enable soft delete, you specify how long Azure Storage should retain a soft-deleted blob. Any soft-deleted blob version remains in the system and can be undeleted within the soft delete retention period. For more information about blob soft delete, see [Soft delete for Azure Storage blobs](storage-blob-soft-delete.md).
 
-When you enable soft delete, you specify the retention period for soft-deleted data. Any deleted blob version remains in the system and can be undeleted within the soft delete retention period.
+### Deleting a blob or version
 
-When both blob versioning and blob soft delete are enabled, modifying or deleting a blob creates a new version instead of a soft-deleted snapshot. This  version is not in the soft-deleted state, so it is not subject to the retention period for soft-deleted data and is not deleted permanently when the retention period elapses.
+Soft delete offers additional protection for deleting blob versions. If both versioning and soft delete are enabled on the storage account, then when you delete a blob, Azure Storage creates a new version to save the state of the blob immediately prior to deletion and deletes the current version. The new version is not soft-deleted and is not removed when the soft-delete retention period expires.
 
-To remove a version, explicitly delete it using the version ID. When a version is deleted while soft delete is enabled, that version becomes a soft-deleted version. Soft-deleted versions are permanently deleted after the soft delete retention period has expired. The following image shows how a version is deleted when soft delete is enabled.
+When you delete a previous version of the blob, the version is soft-deleted. The soft-deleted version is retained throughout the retention period specified in the soft delete settings for the storage account and is permanently deleted when the soft delete retention period expires.

-You can restore a soft-deleted blob version by calling the [Undelete Blob](/rest/api/storageservices/undelete-blob) operation during the soft delete retention period. Once the retention period has elapsed, the blob version is permanently deleted.
+If both versioning and soft delete are enabled on a storage account, then no soft-deleted snapshot is created when a blob or blob version is modified or deleted.

+### Restoring a soft-deleted version
+
+You can restore a soft-deleted blob version by calling the [Undelete Blob](/rest/api/storageservices/undelete-blob) operation on the version while the soft delete retention period is in effect. The **Undelete Blob** operation restores all soft-deleted versions of the blob.
+
+Restoring soft-deleted versions with the **Undelete Blob** operation does not promote any version to be the current version. To restore the current version, first restore all soft-deleted versions, and then use the [Copy Blob](/rest/api/storageservices/copy-blob) operation to copy a previous version to restore the blob.
