Serverless Backup Architecture: Building Pure Peer-to-Storage Resiliency

In modern software design, “serverless” usually refers to cloud-hosted function compute platforms (such as AWS Lambda). In the context of YourKeep’s data resilience architecture, serverless means something far more radical: The complete and total absence of any intermediary server between your machine and storage media.

Traditional backup applications rely heavily on centralized vendor servers to manage user logins, track block deduplication indexes, negotiate encryption handshakes, and route data chunks.

When that central server goes down, is breached, or goes out of business, your ability to recover your data is permanently destroyed.

The Peer-to-Storage Paradigm

YourKeep implements a pure Peer-to-Storage Architecture:

[ User Workstation (Compiled Native Code) ]
                      │
   ┌──────────────────┼──────────────────┐
   ▼                  ▼                  ▼
[Local Drive]   [WebDAV Target]    [S3 Storage]
(Fragment 1-3)  (Fragment 4-6)     (Fragment 7-10)

1. Client-Side Native Execution: All cryptographic hashing, symmetric encryption (AES-256-GCM), and erasure coding matrix calculations execute locally in host memory.
2. Self-Describing Containers: Binary headers inside each fragment embed all necessary metadata, eliminating external database dependencies.
3. Passive Storage Interoperability: Storage targets require zero custom backend code or active daemons.

Why Serverless Architecture Guarantees Longevity

Because there are no central servers to maintain, pay for, or keep alive, YourKeep archives have no expiration date. Your ability to restore your files 30 years from now depends solely on open mathematics and your own credentials—guaranteed forever.
