Credit Union Project Pays Off: Page 3 of 4

A credit union's data must not only be backed up and protected, but its recovery must be quick and uncomplicated. RealTime technology brings a whole, new dimension to backup and recovery with its ability to restore accurately and verifiably any size database or application data files within minutes.

When an error or failure occurs in a production server, RealTime provides recovery to any point in time with reduced exposure to data loss. Restores can be trial-tested in a testbed-recovery server before being applied in production, according to the company. In a simulated recovery test, the credit union had the primary host operational again within approximately 20 minutes.

This almost-instant recovery application, which is a continuous, nonintrusive hot-backup process that produces a constant, running record of application activity in real-time, is compatible with the IBM AIX system Silver State had in place. Recovery is not dependent on a point-in-time snapshot, but uses a constantly rolling "movie" of data that leaves no gaps in saved information. The data is tagged, allowing users to roll back or "undo" to a point in time before corruption occurred, thus eliminating the need to rebuild the data structure.

At a cost of roughly $65,000, which includes the software, hardware and services, according to Sato, "The solution we provided allows easy and quick recovery of stored information with just a few mouse clicks, and it can be done by anyone since it doesn't require any knowledge of databases or technical know-how."

The D2D backup-and-recovery application resides at the credit union's IBM H-80 RISC server's main processor in its Las Vegas headquarters, and in an IBM P-640 Unix backup server in a branch office located 20 miles away. Approximately 9 GB of data is being protected over a wireless microwave link that runs on its own dedicated network between the two computer sites. The network is capable of 2.5 Mbps to 2.8 Mbps throughput of encrypted data. The centralized backup replaces the tape-backup method previously used.
