We needed to decrease our reliance on tape. Before purchasing, verify that the storage and servers are compatible.
Certification is required for servers. Falconstor is a software package that will only be supported on certified devices – this limits the range of servers and storage that are supported. Although certification is available, the product matrix is limited to specific devices that have achieved their storage or server certification.

Overview

FalconStor Virtual Tape Library (VTL) with deduplication is a disk-based backup solution that optimizes backup and restore, improving performance and enabling rapid remote disaster recovery (DR). This solution bridges legacy backup with a more flexible data protection paradigm through a disk-based architecture that reduces physical storage needs and costs.
FalconStor

DeDupe SG™ is a complete, turn-key solution with all the necessary software and hardware leveraging Nexsan’s highly efficient storage combined with FalconStor’s high performance deduplication software engine (File-interface Deduplication System - FDS). DeDupe SG represents the next generation in data deduplication by reducing capacity costs while greatly improving operational efficiency.

DeDupe SG delivers performance that is 20% to 100% faster than competitive vendors by combining the latest high speed CPU processing technology with Nexsan’s high speed RAID subsystem. Not only is it faster, DeDupe SG is smarter by first writing and storing backups on its high speed disk cache (deduping at a later time or concurrently) so that backup tasks are completed in a fraction of the time.
