Azure Blob Versioning automatically maintains previous versions of an object and identifies them with version IDs. You can list both the current blob and previous versions using version ID timestamps. You can also access and restore previous versions as the most recent version of your data if it was erroneously modified or deleted by an application or other users.
We have expanded the preview regions to include East US 2, Central US, West Europe, and North Europe. You can start previewing this feature on any existing or new General-purpose (GPv2) storage accounts in those regions.
