EMC Computer Systems has announced an enterprise storage software package which aims to take the strain out of overnight data backup.
Called TimeFinder, the software enables users to create multiple copies of their mainframe and open systems production data for purposes such as backups, Year 2000 testing, Euro Currency conversion, data warehousing, decision support and application development.
Overnight data backup can be an expensive and disruptive operation, often necessitating the shutdown of mission-critical systems while data is copied to tape. TimeFinder is said to overcome the problem by enabling backups and other processing activities to be done at any time, and in a way that is invisible to users.
TimeFinder is based on EMC's Intelligent Storage Architecture. It extends the technique of standard data mirroring, which involves one original disk and a second mirror disk. Instead, TimeFinder creates multiple and individually addressed copies of a disk, where each copy can be used for separate and independent tasks. Once these tasks are finished, the volume can be resynchronised with the host, if necessary.
"Our customers' pursuit of 24x7x365 data availability for business-critical applications is paramount," said Mike Maunder, EMC's UK and Ireland marketing director. "With TimeFinder, they can eliminate most systems interruptions, keeping their information on-line and accessible."
A second product, called DataReach, enables DB2 mainframe data to be extracted and transferred directly to an open systems database. It was developed jointly between EMC and BMC Software.
The product works without using mainframe or network resources and, according to EMC, is up to five times faster than traditional methods. The first implementation of the system, available now, enables mainframe MVS/ESA DB2 database information to be accessed and loaded onto an Oracle database running on an HP-UX system.
