What Usenet Share actually does.

Encrypted backup, remote storage, archive management, and data migration — with the protocol-level capabilities and numbers behind them: AES-256-GCM, SHA-256 per-file verify, 60 concurrent NNTP connections, disk images of any size, AI training datasets streamed straight to disk, and 20 TB / 3.5M+ files / 30M+ articles stored end-to-end with zero corruption.

00 / Mount & Restore

Open an archive like a network share.

Mount archives as a network share

Open a stored archive and you see a real folder tree — directories, filenames, sizes — the same way an SMB or NFS share appears. No NZB, no manifest, no manual assembly.

Selective or complete restore

Restore one file, a subfolder, or the whole archive. You only pull down what you choose; the rest stays in remote storage until you need it.

Disk images, browsed like folders

A stored disk image appears as a mountable, browsable folder tree. Extract files selectively or stream the whole image to a target disk.

01 / Smart Storage & Speed

Optimised for file-heavy backups & datasets.

Smart small-file packing

Millions of tiny files would mean millions of tiny uploads. Usenet Share packs files under ~500 KB into single Usenet articles, then unpacks them perfectly on restore — dramatically faster on file-heavy backups.

Big files chunked in parallel

Large files are split into fixed-size chunks and moved across 60 concurrent NNTP connections. Matches per-IP caps at Newshosting, Tweaknews, and Eweka.

No archive-size limit

Multi-GB individual files inside multi-TB archives. The architecture has no theoretical cap — verified with 20 TB / 3.5M+ files end-to-end.

02 / Write to Disk

Stream disk images and archives straight to disk. Zero staging.

Create disk images of any size

Build raw, .img, or .iso disk images from folders or block devices and store them on Usenet. There is no practical size limit — images can be as large as your dataset.

Direct-to-disk streaming

Write to Disk pipes an archive or disk image directly to a target disk or block device on restore. You never need free space equal to the image on your system drive first.

Mount & extract images

Mount stored disk images read-only to browse contents, or extract selected files without materialising the whole image.

Pause / resume + crash-resume

Interrupt or crash mid-write and it picks up exactly where it stopped. Nothing to re-download, nothing to reconcile by hand.

Data migration between sites

Migrate 20 TB of data or a disk image onto a target drive at another site without needing 20 TB of staging free on the machine running the restore.

AI / ML

Store training data. Stream to model servers.

Host multi-terabyte training datasets

Datasets too large for object-store egress budgets can be stored on Usenet. The app handles chunking, packing, and redundancy the same way it does for folders and disk images.

Stream to a model server or training node

Mount or pipe the stored dataset directly to a training node. The bytes flow as needed; you never need to stage the full dataset on the receiving machine first.

No per-GB egress from a cloud vendor

A flat Usenet provider fee covers the transfer. For large AI datasets, that can mean the difference between a predictable bill and a five-figure egress surprise.

Same encryption and verification

AES-256-GCM in transit and at rest on Usenet, plus SHA-256 verification. The dataset is protected by the same keys and integrity checks as any other archive.

03 / Security

Encryption you can audit.

AES-256-GCM end-to-end

Data is encrypted on your machine before it hits your Usenet provider. Without the archive's key, the bytes on Usenet are random noise.

Three access levels

Private, password-scoped, or key-scoped for specific machines. Key-scoped archives restrict decryption to keyholders you added — even with the URI, others get useless ciphertext.

No vendor sees your data

We don't see your files, archive URIs, or usage. We can't — there's nothing on our infrastructure to see. Even your Usenet provider only sees ciphertext.

04 / Speed

Built for wire-speed.

60 concurrent NNTP connections

Matches per-IP caps at Newshosting, Tweaknews, Eweka. Saturates gigabit uplinks where the provider supports it.

Custom-modified NYUU upload

Tuned for batch performance and resume safety, not generic NZB posting workflows.

Native C++ downloader

Not a Python re-implementation of the wheel. C++ speed on the read path, Python glue everywhere it doesn't matter.

05 / Reliability

Engineered for don't-touch-it backups.

SHA-256 verified at every step

Every file is hashed pre-upload and re-hashed on restore. Mismatches trigger automatic re-fetch from redundancy.

Resume-safe

Network drops, app crashes, even reinstalls don't lose progress. Auto-resume picks up exactly where it stopped.

Auto-repair from redundancy

If a Usenet article is missing, the app pulls a redundant copy. If that's missing too, you get an operator-actionable error — not silent corruption.

Verified at massive scale

20 TB dataset, 3.5M+ files, 30M+ articles stored and verified end-to-end with zero data corruption. Every file category: streaming, packed, unicode, symlinks, hardlinks, boundary sizes.

Archive retention management

Archives persist as long as your Usenet provider retains the newsgroup. The app tracks retention per archive and warns you before expiry so you can re-publish and avoid data loss.

06 / Access levels

Three access levels for your archives.

Private URI

Only holders of the archive URI can restore. Treat it like a password.

Password-scoped

URI plus a password required to open the archive.

Key-scoped

Only machines whose public key you added can decrypt. Even with the URI, non-keyholders get useless ciphertext — useful for team backups and multi-site restore.

07 / Integrations

Fits your existing pipeline.

S3-compatible gateway

Point any S3 SDK or existing backup tool at Usenet Share — objects are stored on Usenet. No AWS bill, no egress.

SABnzbd + Newznab shims

Automation stacks that speak Newznab / SABnzbd (Radarr, Sonarr, and others) talk to Usenet Share as an indexer and download client without any changes.

Full CLI

Headless publishing, downloads, key management, and hardening — everything the dashboard can do, scriptable.
