Business data is the lifeblood of a modern organization. IT’s responsibility is to ensure data is continuously available and can be quickly recovered in case the active copy is damaged or unavailable. That means backing up data belonging to AIX, Linux, UNIX, Windows and, increasingly, data belonging to applications that run under Linux on System z.
An important message emerging in the IBM New Enterprise Data Center (NEDC) initiative is that a data center is no longer defined by the bounds of four walls. IT organizations must recognize their data center team now has responsibility for an interconnected set of critical components that must work together, but which are often geographically separated. No matter where data resides, the requirement remains the same: protect that data by moving a copy from each disparate server to disk or tape, somewhere it will be safe and available for a quick recovery. The challenge is finding the right combination of hardware and software to do that reliably, efficiently, securely, quickly, and economically, while causing the least amount of disruption and preferably with an automated and unattended process.
Centralizing and consolidating the backup process is key to meeting this challenge. Instead of needing to manage backups on each individual and often geographically dispersed server, your staff can back up large numbers of servers— from a single server, as a single job, saving time and aggravation.
All enterprise data protection solutions face limitations (e.g., client operating system disk access, network transport speed, backup server operating system disk/tape access) that can affect their ability to perform consistently. Mainframe systems have been centralizing and consolidating backup for many years. Today, there are significant advantages to centralizing enterprise open systems backup and administration by employing a backup server running on an IBM System z.
Specifically, the strengths of the IBM mainframe are its well-proven reliability, consistent operational integrity, superior reporting, and unassailable security.
Data protection applications running on a System z take advantage of these well-documented strengths to provide a flexible, efficient, high-performing backup/ restore solution. Additionally, employing the mainframe for open systems data protection helps an organization leverage the investments it has already made in a disciplined, well-trained staff as well as existing disk and tape resources.
The common advantages of z/OS-resident enterprise data protection solutions are that they provide a predictable, reliable, secure backup and recovery. There are several ways to provision a z/OS environment to achieve these cost-efficiency and elapsed time savings.
Three Different Transport Mechanisms
The System z environment supports three transport mechanisms for an enterprise data protection solution to move data from an open system disk to a mainframe backup server:
• On-network transporting data across a TCP/IP communication network
