Features

Engineered for resilience

Reed-Solomon Erasure Coding

Split files into N shards — only K are needed to restore. Lose some shards? No problem. Your data is mathematically recoverable.

AES-256 Encryption

Optional end-to-end encryption before splitting. Even if every shard leaks, your data stays unreadable without the key.

Multi-Cloud Distribution

Scatter shards across 14+ cloud providers — Google Drive, Dropbox, OneDrive, S3, MEGA, pCloud, and more. No single point of failure.

Parallel & Chunked Transfers

Multi-threaded uploads and downloads with chunked acceleration. Saturate your bandwidth, not your patience.

SHA-256 Integrity Verification

Every shard is checksummed. Verify integrity across all cloud providers before restoration — detect corruption instantly.

Self-Healing Repair

Missing shards? Download the surviving ones, reconstruct the missing pieces, and re-upload — all from within the app.

Interface

See it in action
