FalconStor Virtual Tape Library (VTL) emulates physical tape. VTL writes to a disk system to deliver tape-based backup and archives at high speed.

Single Instance Repository (SIR) deduplication works across the global repository to reduce storage requirements; users can choose inline, turbo (concurrent), or post-processing to best suit their backup needs. FalconStor uses two types of compression: software compression using the LZO algorithm on the VTL server, and hardware compression using compression/data reduction cards. Recent Evaluator Group tests demonstrated a 7:1 reduction ratio on single-node FalconStor VTL with deduplication.

VTL usable capacity scales from entry-level 1TB up to 2PB with VTL/SIR cluster gateway, and supports up to 128 virtual tape libraries, 1024 virtual drives and 250,000 virtual tapes.

FalconStor is hardware vendor-agnostic so users can customize hardware configurations without vendor lock-in. FalconStor demonstrates 3X-6X better price/performance ratio over its leading competitor, although multi-year deployment upgrade costs can add significantly to TCO. An independent upgrade path separately upgrades compute, storage, conductivity and application software.

FalconStor VTL also supports tape-based backup with the NDMP Backup Support option, which moves backup data from a NAS directly to the virtual tape library.
