What is Plakar?

Plakar is an open-source backup solution powered by Kloset and ptar. It creates snapshots of your data, stores them in an encrypted and deduplicated store, and lets you inspect, verify, and restore them later.

Plakar stores backups in a Kloset, an open-source, immutable data store that enables the implementation of advanced data protection scenarios.

Through integrations, Plakar can back up and restore databases, Kubernetes workloads, object stores, and other sources alongside regular files.

What sets Plakar apart:

snapshots are browsable: you can inspect their contents, diff two snapshots, or restore a single file without touching the rest;
every snapshot is independently verifiable without restoring anything;
backups are deduplicated and compressed, so keeping many snapshots does not multiply storage costs;
encryption covers both data and metadata, with an audited cryptography implementation;
Plakar is extensible through integrations for additional sources, storage backends, and destinations.

Plakar can be used from the command line or through its built-in web UI.

More with Plakar

Archives. You can export one or more snapshots as a .ptar archive using plakar ptar. A .ptar file is a self-contained, deduplicated, compressed, and encrypted archive.

Integrations. Plakar supports additional backup sources and storage backends through its package manager. Available integrations include PostgreSQL, MySQL, etcd, Kubernetes, S3-compatible object stores, and more.

bash

plakar pkg add <integration>

Distributed stores. Kloset stores can be synchronized across locations to implement 3-2-1 backup strategies or more advanced push, pull, and sync workflows across heterogeneous environments.
