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
Community powered, trusted by teams
There must be a way to ensure backups remain accessible 10 or 30 years from now. Built with transparency, tested by the community, and trusted for critical infrastructure.
Open source
Plakar is built by a global community
of engaged developers, SREs, sysadmins and
platform engineers.
Write your own plugins, contribute to the codebase, or just help us.
Trusted by great teams
Chosen by teams who can’t afford to lose data or sleep.
Plakar stories
Engineers thought, release notes and data protection last news
It doesn't make sense to wrap modern data in a 1979 format, introducing .ptar
.ptar is our own archive format, a self-contained kloset, a container for your data. You end up with a standalone file that provides deduplication, compression, encryption, with all of the fancy features of a kloset store !
Plakar v1.0.2 was released: mostly S3 improvements !
Plakar v1.0.2 adds an automatic security check for new critical releases. It also fixes relative-path resolution when using an agent, plus delivers dramatic S3 performance and memory improvements for faster, more reliable backups.
Introducing Plakar v1.0 to redefine Open-Source Data Protection with $3M funding
Immutable, queryable, encrypted snapshots with context and integrity — Kloset redefines how data is stored, verified, and reused…
