Kloset store
An immutable, encrypted store for your snapshots, on storage you own.
Learn morePlakar creates encrypted, deduplicated, self-contained snapshots on storage you own. One binary, zero-knowledge, no lock-in.
Backups fail exactly when you need them most.
Legacy tools encrypt at rest, so the backup server, the network, and the storage provider still see your data and hold your keys. Zero-trust can't be an afterthought.
Encrypt with traditional tools and they can no longer deduplicate, so every backup is a full transfer and storage and egress costs balloon.
Closed archives and appliances put a vendor between you and your own data. Your backup should outlive any vendor, cloud, or appliance.
Your data becomes a Kloset.
Plakar reads from your sources, then chunks, deduplicates, compresses, and encrypts in a single pass. The result is a Kloset: an open, self-contained store of snapshots on storage you own. Keys never leave your machine, and every snapshot is a logical full you can verify.
What you protect
One open binary
Keys never leave your machine.
Every action is a command
On storage you own
Open format. Readable and restorable without Plakar.
Everything you need to back up and restore with confidence.
An immutable, encrypted store for your snapshots, on storage you own.
Learn moreDeduplicate and compress before data leaves your system, so each new snapshot stores only what changed.
Learn moreIndependent, tamper-evident snapshots you can delete without breaking newer ones.
Learn moreRestore to the original location or a new destination, a single file or a full snapshot.
Learn moreBack up filesystems, PostgreSQL, MySQL, S3, SFTP, Notion, and more.
Learn moreBrowse, search, and restore snapshots from a local web UI with plakar ui.
Learn moreSchedule backups with cron, systemd, launchd, or Task Scheduler, and enforce retention with plakar prune.
Learn moreOpen under a permissive license. One binary with a clean CLI, API, and SDK.
Learn moreBacked by the people who built modern infrastructure.
Finally a pragmatic, modern replacement for TAR. It is called PTAR, and it looks dope.
Plakar's architecture replicates a lot of the infrastructure Apple built for iCloud Backup: chunking and encryption client-side.
The rise of agentic AI compels us to rethink the resilience primitives of large, dynamic, and distributed infrastructures.
Runs on your machines, writes to your storage.
Self-hosted by design. Your data and keys stay on infrastructure you control.

Nestor saved you a seat.
Plakar is built in public. Drop into our community calls or a Discord hackroom, organize a meetup, improve the docs, or ship your first integration. Nestor will be there, probably counting chunks.
"You wrote your own backup script? Bring it to the next community call. We need to talk."
Nestor, every single weekYour first snapshot is one command away.
Install Plakar, create a Kloset, and back up a folder in under a minute. Open, self-hosted, and yours to keep.
