Hiberden is LTO tape archive software for managing petabyte-scale data with 3-2-1 backup functionality across LTO tape, local disk, NAS, and cloud storage in a single operation. It tracks all archives in a unified catalog, making 3-2-1 backups the default workflow. A verification system ensures data integrity by validating copies with checksums, while disk and NAS copies undergo continuous re-verification to detect decay. LTO tape offers cost-effective offline storage, local disks enable fast restores, and network shares use SMB and NFS protocols. Cloud storage supports S3-compatible providers, with credentials stored locally. A virtual tape drive allows workflow testing, and archives can be restored from any source. Hiberden integrates with AI assistants for natural language queries, with configurable permissions and audit trails. It operates offline using open formats like LTFS, with tapes written in LTFS and disk copies accessible without the software.
