Description
The promise of maximizing IT investments while minimizing complexity has resulted in widespread adoption of server virtualization. In fact, VMware users are now deploying nearly half of their new servers as virtual servers, rather than as physical servers. That said, rapid adoption of server virtualization has brought with it a variety of challenges in backup and data protection.
IT administrators have traditionally backed up their physical servers with backup agents on each server, with the backup agent installed on top of the operating system (OS) running on the physical server. Each backup agent had its own physical server on which to run, and could access all the resources belonging to that physical server without undue concern for over-utilizing the physical server.
