If you extract your Dynamics 365 attachments to Azure Blob, you need to plan for disaster recovery. What if something happens and your attachments are accidentally deleted?
Azure Blob now supports Soft Delete. When enabled, deleted data can be retained and restored for up to 365 days.This feature is off by default.
Without soft delete, deleted data cannot be recovered, even by Microsoft support.
