How do you backup a Microservice? You dump its database. How do you backup an entire application decomposed into microservices? In this paper we discuss the tradeoff between the availability and consistency of a microservice-based architecture, when the backup of the entire system is being performed. We demonstrate that service designers have to select two out of three qualities: Backup, Availability and/or Consistency (BAC), and discuss how to deal with consequences such as broken links, orphan state and missing state in practice.
