It is all well and good to choose the best archiving technology that most securely stores data at the primary site, but if that store is destroyed because of fire, flood or other catastrophe, a remotely stored copy is a godsend. The use of removable media has always been seen as the lowest cost option in creating a disaster prevention strategy. Media is physically transported to a separate offsite store or fire safe.
With the increase in speed and decrease in cost of external network links, replication of archived data to a remote site has become more popular. It does mean purchasing double the storage capacity, one for the local copy and one for the remote copy, but the benefit is faster recovery from the loss of the primary copy, store or site. Another method would be to replicate to cloud storage.
QStar Archive Replicator software replicates data to up to four archive storage technologies, using either proprietary or industry standard file systems. These archives can be located within a single site or across multiple geographic locations. This functionality gives organizations the flexibility to employ blends of storage technologies, creating a hybrid archive, which will fit their individual archive and disaster prevention requirements. In addition, this solution prevents disruption and promotes cost savings by automatically replicating to newly added storage, without the need for migratory software.
QStar Data Director software uses block-based synchronous mirroring technology to ensure that data is continuously written on two storage systems within a site or across the globe. Data Director is available with 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).
