About this release

QoreStor is a software-defined secondary storage platform based on Quest’s proven DR Series Appliance’s resilient deduplication and replication technologies. With QoreStor, you can break free of backup appliances and accelerate backup performance, reduce storage requirements and costs, and replicate safer and faster to the cloud for data archiving, disaster recovery and business continuity.

QoreStor supports all of the major backup software applications in use today and can lower your backup storage costs to as little as $.16/GB while reducing your total cost of ownership. (For a complete list of supported backup software, see the QoreStor Interoperability Guide). QoreStor achieves these results using patented Rapid Data Access (RDA) technology as well as built-in, variable block-based deduplication and compression.

QoreStor helps you to:

  • Reduce on-premises and cloud storage costs with industry-leading deduplication and compression.
  • Accelerate backup completion with protocol accelerators and dedupe.
  • Shrink replication time by transmitting only changed data.
  • Improve data security and comply with FIPS 140-2.
  • Maximize return on investment for existing data protection technologies.
  • Lower total cost of ownership through all-inclusive licensing.

QoreStor is a hotfix release of QoreStor with defect resolutions and minor enhancements. See What’s new in this release for more information. See Resolved issues for information on issues resolved in this version.
