//Kloset, the core of Plakar

Immutable by design. Portable by default.

Every snapshot is encrypted, self-contained and verifiable. Kloset makes backups ready for cold storage and hardened environments.

  • Versioned & encrypted snapshots
  • Full context remain available: file tree, metadata, audit trail
  • Zero modification risk thanks to immutable logical storage layer
//Cold storage & long-term protection

Immutable backups, even on tape.

Plakar supports ultra-durable long-term storage strategies, including S3 Glacier and magnetic tape systems.
Thanks to ptar, Plakar can export snapshots as TAR files preserving the same properties as Kloset — including immutability, integrity metadata, and full context.

  • Use Glacier for air-gapped, low-cost, immutable storage
  • Export snapshots to tape without losing metadata or verifiability
  • Browse or validate archives before restoring, even offline
“With ptar, every backup becomes a self-contained, verifiable archive — perfect for tape, vaults, and legal hold.”
