HuskHoard
What it is
HuskHoard is a Linux tool for moving cold data to LTO tape, spinning drives, or cloud storage while keeping files visible to the operating system. Its policy engine can classify files by age, extension, or directory rules. When an application requests a stubbed file, Linux fanotify can trigger its recall. For video workflows, StreamGate serves content from tape or S3 through a local HTTP bridge with range requests; the site names Plex, Jellyfin, and VLC as compatible players. HuskHoard tracks file versions for individual-file rollback, and a scheduled BLAKE3 scrubber checks offline storage. Payloads use Zstd streams verified by BLAKE3 and can be extracted with dd and zstd. It supports NVMe drives, HDD, LTO-5 through LTO-9 tape, and S3-compatible cloud storage, with rclone replication to 40+ providers. The single CLI binary runs in user space without kernel modules or root daemons. The open-source core is free under AGPL v3 and requires Linux kernel 5.1 or later.
For and against
For
- Keeps archived files visible to the operating system
- Recalls stubbed files through Linux fanotify
- Supports individual-file version rollback
- Scheduled BLAKE3 checks verify offline storage
- Free open-source core under AGPL v3
Against
- Requires Linux kernel 5.1 or later
- Web dashboard and Prometheus integration are coming soon
- Advanced replication policies and dedicated SLA support are coming soon
The verdict
HuskHoard brings tiering, recall, version recovery, and integrity checks to cold-data management on Linux. Its core is free, but the listed enterprise features are still coming soon.
Who it suits
HuskHoard suits Linux users managing cold data across local drives, tape, and S3-compatible storage. Its StreamGate features may also suit media pipelines that serve video from tape or S3.
