Object storage that just keeps your bytes.

S3-compatible buckets, client-side encryption, incremental sync. Your backup client uploads only changed blocks — no dedupe surprises, no egress traps.

Incremental sync

Block-level diffs over a persistent HTTPS channel. Large restores stream without re-chunking.

Client-side encryption

Keys never leave your machine. We store opaque blobs — deduplication happens before upload.

S3-compatible API

Point any existing tool at our endpoint. No SDK lock-in.
