Effortless open source backup platform
Plakar is an open-source backup and restore solution designed to simplify data protection for businesses of all sizes. It protects anything—from local files to multi-cloud AI pipelines—while keeping every snapshot lean, encrypted, and instantly recoverable.
Plakar stores data in open formats readable by open-source code, supports deployment on-premises or across AWS, Google Cloud, Azure, and OVHCloud, and allows delegation to MSPs via the Vault Protocol while keeping encryption keys with the user. This ensures portability and prevents proprietary chains.
Plakar Enterprise aggregates metadata from all agents to map real-time protection status, identify blind spots and unbacked-up assets, and enforce compliance across on-premises, cloud, and SaaS environments. This transforms backup from fragmented operations into an audit-ready, unified strategy.
Plakar offers cryptographic integrity proofs and entropy analysis to detect high-entropy anomalies typical of ransomware before it spreads. Users can mount snapshots as filesystems or browse terabytes via UI without restoring, enabling fast verification and business logic testing.
Plakar provides native connectors for PostgreSQL, MySQL, Notion, Dropbox, Google Drive, OneDrive, and S3, plus an open integration architecture for custom sources. This eliminates brittle custom scripts and extends protection to assets living outside traditional filesystems.
Plakar's Kloset deduplication engine performs high-density deduplication before encryption, achieving >100:1 efficiency ratios. This solves the traditional problem where encryption blinds deduplication, allowing users to enforce zero-trust security without exploding storage budgets.
