What does Plakar do?

Plakar is an open-source backup and restore solution designed to protect data across cloud, SaaS, and on-premises environments. It performs client-side encryption and deduplication before data leaves the source, ensuring zero-knowledge privacy while maintaining storage efficiency. The tool supports multiple storage backends including S3, local storage, and SFTP, allowing organizations to maintain full control over their backup infrastructure.

What sets Plakar apart is its ability to deduplicate encrypted data through its Kloset engine, solving the traditional trade-off between encryption and storage efficiency. Users can mount snapshots as filesystems for instant browsing without full restoration, and the system provides cryptographic proofs of data integrity. The enterprise version adds governance features that provide a unified view of backup posture across an entire organization.

Plakar benefits system administrators and DevOps teams who need to secure diverse data sources while maintaining compliance and reducing storage costs. It's particularly valuable for organizations handling sensitive data that requires strong encryption guarantees without sacrificing storage efficiency. The open-source nature ensures transparency and avoids vendor lock-in, making it suitable for both self-hosted deployments and managed service provider scenarios.
