Mirror writing eliminates the risk of data loss associated with a media failure. Also, by mirroring data to an optical jukebox or tape library at remote locations, QStar Data Director meets the requirements for data center operations requiring 24 x 7 availability.
Additionally, QStar Data Director automatically satisfies regulatory requirements for storing a second copy of data at an off-site location, eliminating the need to duplicate data at the production site and manually ship optical media or backup tapes to another site.
The archive software can be installed on user’s choice of server supporting Windows, Linux, UNIX and Mac environments. It is easily scalable from 1 terabyte to multiple petabytes.
QStar Data Director is recommended for:
Using QStar Data Director with an optical jukebox or tape library to store data on non-erasable, non-rewriteable media types such as Blu-ray and Ultra Density Optical, or LTO WORM tape, in order to comply with regulatory requirements for data retention. Alternatively, if using rewritable media systems, such as RDX, Retention Management can be used to secure files for specified time periods.
Using QStar Data Director with an optical jukebox or tape or RDX library to store data at primary and secondary locations with automatic failover and recovery in the event of a system failure or an actual disaster. Additionally, scheduled maintenance can be performed by intentionally shutting down the optical jukebox or tape library at either location, thus initiating a temporary planned failover to the alternate site.
Using QStar Data Director with an optical jukebox, or tape library with secure, reliable, write-once or re-writable media types such as Blu-ray, Ultra Density Optical, RDX or LTO tapes, provides long-term accessibility to corporate data at a very low cost, while mirroring that data at a secondary data center. These removable media types all have media life times of greater than 30 years.
Highlights of QStar Data Director:
All highlights of QStar Archive Manager plus the following:
• Data Mirroring – Continuously performed at a transactional level, files on the primary and secondary volume sets are always exactly duplicated. The volume sets may be in different optical jukeboxes or tape libraries and can be geographically located anywhere on a corporate Wide-Area-Network.
• Hot Standby – If the primary volume becomes unavailable, read and write requests will still be processed from the secondary site, eliminating data loss and productivity decreases during the period of downtime.
• Automatic Re-synchronization – When the unavailable volume set becomes available again, new data is automatically synchronized back to the alternate volume, ensuring that both volumes are returned to a replicated status.
