Hiberden is a desktop archiving app that gives you provable 3-2-1 protection for large media libraries. Archive projects to LTO tape (LTFS, with multi-cartridge spanning), local disk, NAS, and S3-compatible cloud from one catalog, and see at a glance which projects are fully covered, at risk, or unprotected. Every file is hashed (SHA-256) at write time, and a copy is only marked Verified after Hiberden reads it back off the media and re-checks every hash, so your catalog is evidence, not a hope. Scheduled verification sweeps re-check copies over time and catch silent corruption before you need the files back. Find any file across every copy instantly, including offline tapes. A built-in MCP server lets AI assistants like Claude answer "is the Johnson wedding safe, and where?" straight from your catalog. Windows 10/11; Linux in beta. Free trial, then a one-time perpetual license with no subscription. Built for studios, archivists, and anyone whose files must outlive their hardware.
