Plakar is an open-source standard for unified resilience, providing a high-performance backup and restore solution designed for Cloud, SaaS, and on-premises data. It aims to decouple data protection from infrastructure constraints, giving users full control from "source to value".

The main features of this tool include:

• Zero-Trust Native Encryption: Plakar utilizes end-to-end encryption that occurs at the source, ensuring zero-knowledge privacy before data is moved or stored.

• High-Density Deduplication: Unlike traditional tools where encryption breaks storage efficiency, Plakar's "Kloset" engine performs deduplication before encryption. This allows for high-density efficiency (up to 100:1 ratios) without compromising security keys.

• Unified Resilience Architecture: It provides a single ecosystem to secure diverse data sources, including on-premise servers, SaaS applications, databases, and Cloud buckets, eliminating the need for brittle custom scripts.

• Extreme Scalability: While traditional architectures may struggle at scale, Plakar is engineered for exabytes with a minimal memory footprint, capable of handling millions of files.

• Native Integrity Proofs: Users can rely on cryptographic proofs to guarantee data integrity and prevent "bit-rot" without requiring a full restoration.

• Searchable and Browsable Snapshots: Backups can be mounted as a filesystem or browsed via a UI instantly, allowing users to query snapshots or provision staging environments without waiting for a full restore.

• Vendor Lock-Free Sovereignty: Data is stored in open formats readable by open-source code, ensuring your backups remain accessible for decades regardless of proprietary platforms.

• Enterprise Governance: The platform offers a governance layer that aggregates metadata to map a real-time protection status, helping leaders identify blind spots and enforce compliance across an entire estate.
