Description
Hiberden is a desktop archiving application developed by Agave Information Solutions, LLC. It maintains a single catalog of archives and copies across four destination types: LTO tape (single drives, via LTFS), local disk, NAS, and S3-compatible cloud storage.
- SHA-256 checksums are recorded per file at write time. A copy is only reported as Verified after a read-back in which the stored media is re-read and re-hashed against the recorded values.
- Scheduled verification sweeps re-check existing copies over time. A copy cannot be promoted to Verified without a full SHA-256 read-back; a faster BLAKE3 pass can sustain or revoke an existing Verified state but can never grant it.
- Coverage status rolls up per project against a 3-2-1 target (number of copies, number of distinct media types, offsite placement), distinguishing verified copies from merely listed ones.
- Tape support is in beta. It is implemented against LTFS command-line tooling rather than direct SCSI control, and as of 2026-07 it has not been validated against physical tape hardware in this implementation. Tape libraries and autoloaders are not controlled by the tool. Multi-cartridge spanning is implemented but is likewise unvalidated on physical hardware, and a spanned write is deliberately not counted toward 3-2-1 coverage.
- Disk, NAS, and S3-compatible cloud destinations are exercised against real storage, including a live S3-compatible server in continuous integration.
- Includes a Model Context Protocol (MCP) server (read-only by default) so AI assistants can query catalog contents, coverage status, and verification history. Listed in the official MCP Registry as io.github.Agaveis/hiberden-mcp.
