A High-Frequency Backup (HFB) Service is an add-on feature that aims to solve specific use cases for backing up your highly transactional, frequently-changing data as often as up to every hour.
HFB protects specific, highly transactional objects, such as financial transactional data, customer support cases, or eCommerce data, which are often created or updated multiple times a day.
