ABSTRACT
This chapter focuses on availability from the perspective of recovery-point objective—that is, backup, snapshot, and continuous data protection—along with security. There are some similarities that common tools, technologies, and techniques can be leveraged to provide availability of applications, data, and data infrastructure resources. Backup and archiving have similarities along with differences. Both archive and backup provide protection to a given point in time, yet have different objectives and intended uses. Archives can be cold and off-line, representing data and applications at a point time or for future needs, including compliance regulations. Change block tracking can be implemented in operating systems, hypervisors, as well as other data infrastructure locations. There are several different security focus areas for data infrastructures. These include physical as well as logical, spanning legacy, software-defined, virtual, cloud, and container data infrastructures.
