Backup Anything. Store Anywhere.
Restore Everywhere.

The open standard for unified resilience.
Secure your Cloud, SaaS and On-Prem data with native zero-trust encryption.

The Math has changed

End-to-end encryption broke the efficiency model of traditional backup.Plakar defined a new architectural standard.

Encryption kills storage efficiency

Standard backup solutions cannot deduplicate what they cannot see. You are forced to choose: explode your storage costs or surrender your encryption keys.
Plakar fixes the math: high density on fully encrypted data.

Backup engines break at scale

Architectures built for gigabytes crumble under petabytes. They consume too much RAM, scan too slowly and inevitably miss your SLAs.
Plakar is engineered for exabytes with a minimal footprint.

Files are just a fraction of your data

Your assets live in SaaS, databases and Cloud buckets. Traditional tools ignore these sources, forcing you to maintain brittle custom scripts.
Plakar builds the open ecosystem to secure any data source.

Plakar Unified Resilience Architecture

Decoupling data protection from infrastructure constraints.From source to value, you are in control.

Open Source
01 / BACKUP

Secure at Source

Deploy backup agents on-premise or use agentless connectors for Cloud & SaaS. Deduplication & encryption happen at the source, ensuring zero-knowledge privacy before data moves.

Open Source
02 / STORAGE

Self-Host or Delegate

Store copies yourself on any disk or cloud, OR delegate resilience to a Provider via the Plakar Vault Protocol. In both cases, your data remains fully encrypted and sovereign.

Open Source
03 / VERIFY

Native Integrity Proofs

Don't assume, verify. Mount snapshots to run business logic tests or rely on Plakar's native cryptographic proofs to guarantee zero bit-rot without full restoration.

Open Source
04 / CREATE VALUE

Recover & Provision

Stop treating backups as dead weight. Trigger full disaster recovery or provision staging environments instantly to fuel your business workflows.

Governance Layer

Plakar Enterprise: Unified Backup Posture

The missing link for C-Levels. Aggregates metadata from all agents to map your real-time protection status. Identify blind spots, unbacked up assets, and enforce compliance across the entire estate.

Total Assets 1,420
Protected 99.9%
Integrity Check PASSED

From blind spots to provable posture

For tech leaders, Plakar Enterprise transforms backup from a fragmented operational task into a unified, audit-ready strategy.

Unified Resilience Posture

Stop guessing what is recoverable. Get one consolidated view of your resilience across On-Prem, Cloud and SaaS. Eliminate coverage gaps before the audit.

Cost vs. Security: Solved

Encryption usually kills deduplication. We fixed the math. Enforce Zero-Trust without exploding your storage budget.

>100:1 Efficiency Ratio

Delegate Ops, Keep Keys

Outsource retention and replication to MSPs or Cloud without ever exposing your secrets. The Plakar Vault Protocol ensures the provider remains blind.

"Plakar reconciles the rigor of Open Source security with the scale of Enterprise needs. It’s the first time we’ve achieved a 70% cost reduction through high-density efficiency, without ever handing over our encryption keys."

Why engineers choose Plakar

Because it combines Open Source transparency with production-grade rigor.Secure by default and built by veterans to fit seamlessly into your DevOps workflows.

1

Trust Nothing Architecture

We assume the network is compromised and the storage is untrusted.

With client-side encryption and immutable snapshots, we don't just "hope" your data is safe; we mathematically guarantee it.

2

The Efficiency Engine

Encryption blinds standard tools. Plakar's Kloset engine performs high-density deduplication before the encryption layer.

Slash your storage costs and network usage without ever exposing a single byte of plain text to the infrastructure.

Searchable & Browsable

Mount snapshots as a filesystem or browse terabytes instantly via the UI without restoring.

Petabyte Scale

Engineered to handle millions of files and massive datasets with a minimal memory footprint.

Integration Architecture

Write your own input/output connectors in your favorite language. The ecosystem is open.

Entropy Analysis

Detect high-entropy anomalies typical of ransomware activity before it spreads.

Vendor Lock-Free

Data is stored in open formats, readable by Open Source code. No proprietary chains.

Immutable & Verifiable

Snapshots are read-only by design. Cryptographic checks guarantee restore integrity.

Kloset schema
This is kloset

Kloset encapsulates each backup into a self-contained, immutable, structured data asset. Like a container that packages an app with everything it needs, Kloset packages data with context, structure, metadata and integrity.

Self-contained

Everything your data needs travels with it. No external dependencies.

Immutable

Once created, a Kloset never changes, ensuring data integrity and security.

Queryable

Inspect and query snapshots without restoration. Instant access.

Portable

Move your Klosets anywhere. Same structure, everywhere.

Kloset does for data what Docker containers did for compute

Kloset for Data

  • Packages data with all metadata and context
  • Ensures consistent data integrity and structure
  • Portable across different storage systems
  • Standardized format for preservation

Docker for Applications

  • Packages application with all dependencies
  • Ensures consistent execution environment
  • Portable across systems
  • Standardized format for distribution
