Data Director expands the archive disaster protection capabilities of QStar Archive Manager software by providing block-based synchronous mirroring technology. It ensures that data is continuously written to two drives/devices within a site or across the globe. QStar’s Data Director software gives customers the choice of multiple real-time mirroring options that include media mirroring within a single library (DDR1), device mirroring within a single site (DDR2), and site mirroring across multiple geographic locations (DDR3).
In addition, in combination with Data Director, STJ / SDJ (Simulated Tape Jukebox) creates simulated tape or optical media on RAID. Using Data Director to mirror between the real and simulated media a blended archive solution is created; with one mirror on disk and one on tape or optical.
Failover capabilities ensure that if the primary archive cannot be accessed, requests are automatically directed to the secondary archive.
Data Director’s disaster prevention capabilities are powered by QStar’s optimized object file system, to facilitate a resilient archive strategy that provides very cost effective and dependable business continuity for the QStar archive platform.
Eliminate the Risk of Data Loss Associated with a Media Failure
Mirror writing eliminates the risk of data loss associated with a media failure. Tape and optical media are manufactured to very high standards but a media failure is still a possibility. If this were to happen, data could be lost. Typically, most administrators would create a second copy of data on another piece of media and remove it from the library, providing a disaster recovery copy. Data Director provides a better solution. The software uniquely creates two synchronous mirrored copies, eliminating any issues associated with bad media.
