Backup Systems Performance & Capacity Design (Cont'd)
THE IDEAL SYSTEM: LOCAL & NETWORKED
(click here to return to Part One of this white paper)
Now that we have examined the relevant components of a Backup Server, we can now dictate what the ideal backup server would consist of.
Local Backup Server
A local backup server does not have to worry about network concerns, since it only needs to back up itself. In general, the Backup Server should not have any applications (e.g., database applications) running when the backup application is running. The ideal hardware configuration would include:
Networked Backup Server
A networked Backup Server needs to be flexible enough to handle unplanned growth. For this reason, the HP Omniback software is the application of choice. HP Omniback has centralized management enabling unlimited growth with distributed backup devices. It incorporates both parallel streaming and interleaving to provide optimum performance. As far as hardware is concerned, the following would be a great start:
SUMMARY
Constructing an optimal backup system for mid-range to enterprise-level customers is not a trivial task. There are a number of factors to consider when suggesting or designing a backup system. It is critical that SE's be educated as to what questions to ask to generate sales. Once the information has been received, the SE can generate a formal backup system proposal which IT professionals can use as a tool to sell the concept to upper management in a very professional manner.

A local backup server does not have to worry about network concerns, since it only needs to back up itself. In general, the Backup Server should not have any applications (e.g., database applications) running when the backup application is running. The ideal hardware configuration would include:
- 200+ Megahertz Processor
- RAID 1/5 Subsystem
- 1 - SCSI Controller per DLT 8000 Drive
- 1 - SCSI Controller per two DLT 4000 Drives or DAT 40 Drives
Networked Backup Server

HP Omniback has centralized management enabling unlimited growth with distributed backup devices. It incorporates both parallel streaming and interleaving to provide optimum performance. As far as hardware is concerned, the following would be a great start:
- 100baseT Backup Clients
- 100baseT Switched Hubs
- 100baseT Network Interface Card(s)
- 200+ Megahertz CPU per Network Interface Card
- 64 MB RAM
- 1 - NIC per SCSI Controller
- 1 - Wide SCSI Controller per DLT 8000 Drive
- RAID 5 Subsystem for Backup Software & Operating System
