We rebuilt the Plakar UI in the open and documented every decision: pnpm + Turborepo, React, TypeScript, Zod, the full TanStack stack, React Aria, Storybook, and testing. A 14-part engineering series for anyone building a serious frontend. https://plakar.link/ui

Can you query PostgreSQL inside a backup without restoring first? We tried two paths: SQL over a filesystem view, and mounting a base backup as a qcow2 copy-on-write disk to query live. A snapshot you can inspect, not just hope restores. https://plakar.link/pgview

The 3-2-1 backup rule is 30 years old: 3 copies, 2 media types, 1 offsite. Most prod environments still violate it. It survives ransomware, cloud outages, and accidental deletes precisely because it assumes any one layer fails. Why it still holds: https://plakar.link/321

Proxmox backs up your VMs with vzdump, but those dumps sit on local storage, unencrypted and un-deduplicated. The Proxmox integration wraps vzdump and stores each backup as a Plakar snapshot: dedup, encryption, portable anywhere. https://plakar.link/proxmox

Managed Postgres backups you can't download aren't really yours. pg_dump + Plakar: portable, encrypted, deduplicated backups over a standard connection. No WAL or filesystem access needed. Restore anywhere with pg_restore. https://plakar.link/pgdump

In case you missed it, Plakar Control Plane is now on AWS Marketplace The off-AWS copy finally becomes affordable: source-side dedup + client-side encryption cut egress and off-site storage to a fraction of the bytes. https://www.plakar.io/posts/2026-07-10/plakar-control-plane-aws-marketplace/

Plakar Control Plane is now on AWS Marketplace. Deploy it in your own AWS account in a few clicks. Your data never leaves your environment. Agentless protection, free plan, no time limit. https://www.plakar.io/posts/2026-07-10/plakar-control-plane-aws-marketplace/

Update homelab : j'ai enfin des vrais backups sur mes containers Proxmox 🙌 Testé Plakar, ça marche nickel, tout est chiffré et part sur mon NAS chaque nuit automatiquement. Et un bot me prévient sur Discord si ça foire. Next step : un backup offsite en plus.

Plakar : un outil Open Source de backup “snapshot-based” qui combine déduplication, compression et chiffrement pour sauvegarder de très grands jeux de données. 👉 Le projet : github.com/PlakarKor... 👉 En savoir plus : https://plakar.io/

Replication propagates state. Backup preserves history. They solve different problems — you need both. https://dub.sh/P8QX1c5

Sinon il y a aussi l'excellente solution française www.plakar.io qui est vraiment impressionnante en terme de performance et de portabilité (via leur 'kloset´).

Plakar | The Open Standard for Backup and Restore

Enterprise ready backups with developer friendly tooling. Encrypted, deduplicated snapshots, instant browsing and restore, and zero knowledge workflows across clouds and on-prem.

S3 durability != backup. It doesn't protect against deletion, ransomware, or corrupt writes that replicate across your bucket. https://dub.sh/kb3cWai

Independent cryptographic audit of Plakar published. Sound design, clean recommendations, all fixes verified. Public report. https://dub.sh/6Fb3KHB

Plakar Control Plane (our commercial product built on top of Plakar) now includes a free plan! On July 7th at 4pm CET, Julien Castets is hosting a live demo and Q&A. We hope to see you there! Register: https://luma.com/p0pi6i7y

We’re officially launching a free plan for 𝗣𝗹𝗮𝗸𝗮𝗿 𝗖𝗼𝗻𝘁𝗿𝗼𝗹 𝗣𝗹𝗮𝗻𝗲, a self-hosted backup management platform with a full web interface providing: 1. A unified view of data inventories 2. Integrations 3. Backup policies and scheduling tasks 4. Secrets management

The 3-2-1 backup rule is 30 years old and still violated by most prod environments. Here's why it holds up. https://dub.sh/TYtwKm4

RTO and RPO: the two numbers that define whether your disaster recovery is real. A clear explainer. https://dub.sh/esXuT8r
